Cement Testing Equipment Cement Concrete

The aggregates consist of sand and gravel which are also tested prior to adding to cement. Due to its weakness in tensile strength, reinforcements are commonly used within the building blocks during the moulding/setting of cement concrete. The reinforcement materials are made in the shape of steel bars commonly called TMT.

TESTING ALKALI-REACTIVITY OF SELECTED CONCRETE

2006-9-25  sensitivity, the method which tests the deformation of the concrete bars including the aggregate at issue and increased al-kali content cement seems to be the most conclusive. However, the test duration up to 180 days is too short, particularly for defining the slow-reactive aggregates reactivity, such as, for example, granites or quartzites.

Testing of Hardened Concrete - Compression, flexural,

Compression test is the most common testing conducted on hardened concrete, partly because it is an easy test to perform, and partly because most of the desirable characteristic properties of concrete are qualitatively related to its compressive strength. The compression test is carried out on specimens cubical or cylindrical in shape.
