Root Cause Analysis of Failures in the Testing of Concrete ...

Concrete is a material used for construction of infrastructure. It is a material which has a high compressive strength but a low tensile strength. Concrete is made by mixing a few other materials such as cement, water, aggregate, admixtures, fibers, polymers, reinforcements etc. in various proportions so as to obtain different grades of concrete. III.

Concrete Blocks and Pavers Mix Design and Manufacturing

manufacture concrete blocks as well as paver blocks of various grades. Concrete blocks up to M15 grade and paver blocks up to M50 grade can be manufactured. They apply extreme vibrations to blocks and therefore are able to make concrete blocks at lower w/c ratio resulting in lower binder content as compared to any other machines.

The effects of mortar strength, grouting, and grout strength on the compressive strength of the prism were discussed. The test results show that the compressive strength of Hblock prisms decreased with an increase of grouting, although the ultimate load of the prisms increased greatly.
