INSITU TESTS

Aggregate

Standard: EN 932-1:1997
Although we do accept samples taken by our clients, we recommend that our technicians carry out this important part of every test to obtain representative samples as this has a major influence on test results.

Standards: EN 1097-5:2008, EN 933-1:2012
These important classification tests assist in supply control as well as in the determination of the characteristics of materials for suitability of use. Results are also used in the production of concrete and asphalt mix designs.

Standard: EN 1097-2:2010
The resistance to fragmentation by the Los Angeles test is the aggregate strength test procedure currently valid in the EN standard test range. We also carry out the Aggregate Impact Value test (AIV), Ten Percent Fines Value (TFV) as well as Aggregate Crushing Value (ACV). Accreditation for these tests is not available since the tests have been superseded by CEN and CENELEC, European Standardization Organizations.

Standard: EN 1097-6:2013
The density is defined as mass per unit volume. We are equipped to carry out multiple concurrent determinations. Test results give insight into aggregate quality and are used in the determination of trial mix constituents.

Standards: EN 933-3:2012 and EN 933-4:2008
The shape of aggregate particles can be classified as either cubical, non-cubical, angular, subangular, subrounded or rounded. Aggregate particle shape is directly proportional to its strength.

Standards: EN1097-3 and EN1097-7
The bulk density of aggregates is the mass of the aggregate required to fill a container of a unit volume. The result of this test may be used in determining mass/volume relationships for conversions in purchase agreements. The bulk density affects the mix design, workability, and unit weight behavior.


The durability and life expectancy of a structure is only as good as the quality of its poorest ingredient

Concrete

Standards: EN 196-6:2010, EN 196-3-2005, and EN 196-1-2005
These properties of cement have a direct relationship to the finished product, both in terms of workability and placement, as well as final product strength.

Standards: EN 12350-1:2009, EN 12350-2:2009, EN 12390-2:2009
Although we accept cubes made by clients, they may have to be rejected unless they conform to rigid standard tolerances. When our representatives are on site, they can report on the workability to the client's representative immediately.

Standard: EN 12350:7-2000
This is an important aspect in the calculation in concrete trial mix design.

Standards: EN 12350-6:2000 and EN 12390-7:2000
All concrete raw ingredients come together to produce concrete of differing properties. Concrete density gives an overall indication of the quality of the raw ingredients and the batching weight per unit volume.

Standard: EN 12390-3:2002
Ultimately, it is the strength of a concrete that dictates its suitability for the element into which it is cast. This is the most important of all concrete analysis.

Standard: EN 206:2013
Concrete mix deisgn in an art in which know-how and experience come together to produce a concrete that performs well in both the fresh and hardened states. Data from the test results on raw materials are processed to find the optimum mix proportions.

We will be applying for accreditation in cement testing as an extension to our scope of accreditation.

Asphalt

Standard: EN 12697-27:2001, EN 12697-13:2000
Whether during or after laying, sampling is a very important part of asphalt analysis since poor sampling may lead to poor result performance.

Standards: EN 12697-32-:2003, EN 12697-1:2012, EN 12697-2:2002, EN 12697-30:2012, EN 12390-7:2009, EN 12697-34:2012
This suite of tests reveal the properties of a batch of asphalt: strength, make up, and flexibility. In turn, they are compared against minimum requirements from the contracting authority.

Standards: EN 12697-5:2009, EN 12697-8:2003
The theoretical maximum specific gravity is the specific gravity excluding air voids in a given sample. These details are used both in the determination of voids in a cored sample as well as during mix design stage.

This test identifies the ride quality of a stretch of road, which, at the end of the day, is what road goers are most interested in. Any undulations in the finished surface are identified.

Standards: , , EN 12697-9:2002
These tests quantify the bond between asphalt layers as well as the degree to which they are compacted. The latter is then compared to the density of laboratory compacted samples which represent the best possible.

Asphalt consists of aggregate and asphalt binder. A mix design determines what quality and amount of raw materials are to be used and what the optimum combination of these are based on the results of tests carried out on the raw materials. When aggregate and bitumen are combined to produce asphalt, the latter performs differently to the properties of its components. Laboratory trial mixes are used to characterize the mixture proportions and to predict the end product properties.

Soil

Standard: BS 1377 Part 2: 1990
A fine-grained soils such as clay can exist in various states which depends on its water content. When water is added to a dry soil, each particle is covered with a film of absorbed water. If the addition of water is continued, the thickness of the water film on a particle increases. This increase permits the particles to slide past one another more easily. The behaviour of the soil, therefore, is related to the amount of water contained. These tests identify characteristics of soils.

Standard: BS 1377-4:1990
This test is carried out to determine the maximum dry density and the optimum moisture content of a soil using heavy compaction. Results are then used to compare compactions achieved on site, determined by the sand replacement density test (see below).

Standards: ISRM Suggested Method for Determination of the Uniaxial Compressive Strength of Rock Materials, ET Brown 1981. ISRM Suggested Method for Determination of the Uniaxial Compressive Strength of Rock Materials, Modified by Annex W, 'Strength Testing of Rock Material' of EN 1997-2:2007
The unconfined compressive strength test is that most commonly used for for strength determination on rock core specimens. Samples obtained by core drilling are trimmed to obtain a length / diameter ratio of 2 to 2.5. The ends of the specimen are trimmed flat and smooth, parallel, and exactly perpendicular to the axis of the core. The specimen is placed in a compression testing machine and subjected to compression with an automatically controlled pace rate. The peak load achieved is divided by the area of specimen to obtain the final result.

Standard: BS1377-9:1990
The SRD test is used to measure the in-situ density of compacted soils using calibrated sand and a sand pouring cylinder. The SRD result is expressed as a percentage of the laboratory MDD (above) results to estimate the degree of compaction of road sub-base materials.

Standard: BS 1377-9:1990 Part 8
A triaxial shear test is a common method to measure the mechanical properties, mainly strength, of clays and other granular materials.

Standard: BS 1377-7:1990
The direct shear test is used to measure the shear strength properties of soil, rock, or discontinuities in soil or rock masses.

At Solidbase we pride ourselves on a reliable service with quick turnaround on test results and reports, with a constant eye on quality.

Other Laboratory Tests

Standard: BS1377-9:1990
We carry out the CBR test as a lab test. It measures the pressure required to penetrate a soil sample with a plunger of standard cross-sectional area. The force required is then divided by that required to achieve an equal penetration on a standard crushed rock material. The better quality the sample, the higher the CBR value.

Standards: EN 772-1:2011, EN 772- 16:2011, EN 1338:2003, EN 1339:2003
Masonry and paving blocks are measured, prepared, and cured for compression testing. A uniformly distributed load is applied and increased continuously to failure. The peak load is expressed as a force / surface area value.

Standards: EN 13748-1:2004, EN 13748-2:2004, EN 10545-4:2014
Depending on the type of tile submitted for testing, the following tests can be carried out:
● Moisture content
● Transverse strength
● Dimensions & appearance
● Water absorption (total and / or face)
● Transverse Strength
● Dimensions & Appearance

Standard: EN 1340:2003
The standard defining tests on kerb specifies the materials, properties, requirements, and test methods for unreinforced, cement bound precast concrete kerb units, channels and complementary fittings, that are for use in trafficked paved areas.

Standard: EN 1008:2002
The suite we carry out for water testing is for suitability of use in concrete. The following tests can be carried out: chlorides, sulphates.

Standard: EN 10002-1:2001
Steel reinforcement bar, or rebar, is embedded in concrete to improve the overall strength of the concrete element it forms part of. Testing is carried out to determine whether the rebar meets specifications required.

Insitu Tests

Standard: DIN 18134: 2012
The plate bearing test is an in-situ test to determine the ultimate bearing capacity of layers of soil that form a carriageway and the potential settlement under load. The test consists of loading a standard diameter plate, unloading it, and subsequent reloading. The settlement corresponding to the load increments applied is evaluated as a load-settlement curve.

Standard: EN 12504-2:2001
The Schmidt hammer is a spring-loaded device which provides rebound valves when the force is applied to a concrete surface. These values are correlated to compressive strength by using the conversation table provided with the hammer. The Schmidt hammer is mainly a surface hardness test and is not designed to give strength indication at depth.

Standard: BS 1881-204:1988
A cover meter is an electromagnetic device that may be used for estimating the position, depth and size of reinforcement buried in concrete.

Standard: EN 1542:2000
The pull-off apparatus produces results that correlate to the compressive strength of the concrete under examination. The correlation is achieved by measuring the force required to pull a metallic disc which has been securely affixed to the surface off the concrete.

Standard:
The Clegg impact soil tester measures the strength of a compacted soil. It is used to identify poorly compacted areas and ineffective compaction of road sub-base. The results are comparable to equivalent in-situ CBR results. Although not as accurate as the CBR test, a Clegg hammer survey can give better coverage and can be used in areas where other tests can't be carried out because of mobilisation and / or setup issues.

Standard: In-house method LOQP Section 6
This test follows an in-house developed procedure in which a concrete surface is struck with a standard weight hammer and the resulting sound evaluated for subsurface voids.
