| Concrete Testing Equipment |
Many Quality Assurance
aspects including production control, efficient materials usage and compliance
with mix designs are dependant upon the effective analysis of cementitious
mixtures. There are a wide range of test which can be carried out. It is important
that the correct design and physical testing of these mixtures is achieved if
good quality products are to be produced with minimum maintenance and
economical production.
The suitability of any concrete to a particular purpose is first assessed whilst the concrete is still paltic or fresh before hardening comences. Tests for fresh concrete ofter focus on the workability of the mix and can be assessed by Slump, Flow Table and Vebe methods.
Modern developments in
mixture designs tend to be more specific to characteristics of the mix under
repetitive load conditions such as permanent deformation and elastic stiffness.
This in turn has led to the development of a range of mix design equipment for
use on both laboratory mould samples and field cores.
Materials Testing Equipment
Ltd offer a sophisticated range of testing equipment complying with the various
test methods, ensuring that accurate and consistent test results are always
obtained. |
|
| Workability |
Workability of concrete is a measure of viscous the fresh concrete mix is. Each specific concrete application should have a specified workability to ensure the operations of handling, placing and compaction can be achieved efficiently.
UK & European standards give guidance on workabilty for different uses.

Compacting Factor
|
30-11310 Compacting Factor
Apparatus, complying with BS1881:Part 103, the equipment is appropriate for
concrete mixes of low, medium and high workability. Consisting of two conical
hoppers fitted with tightly hinged trap doors which help facilitate the falling
of concrete into the cylindrical mould. The frame which the hoppers and mould
are mounted upon is manufactured from rigid steel

Slump
|
30-10220 Slump Cone, spun steel and corrosion resistant. The test is carried out in accordance with BS1881:Part 102, by filling the slump cone with freshly mixed concrete which is tamped with a steel rod in three layers. The concrete is levelled off from the top of the slump cone, and the slump of the sample is measured

Air Entraiment Meters
|
30-10620 Air Entrainment
Meter, Type A , for determining the air content of freshly made concrete as
detailed in BS1881:Part 106 and ASTM C231. The purpose of entraining air in
concrete is to give the required resistance to weathering. The use of chemical
additives to increase the workability of concrete often requires an air content
check to be made
30-10642 Air Entrainment Meter Type A, for mortars as described in
BS4551. Designed to take a 1 Litre sample. The column is calibrated 0-25%.
Supplied complete with calibrating cylinder, spring & support, pump and
plastic tamper
