Again, a better approach is testing aggregate in concrete. Chemical Tests. Alkalisilica Reaction A rapid reliable test for alkaliaggregate reactivity has not yet been developed. Most acceptable tests require long curing times of about 6 months. In this test, the aggregate is ground into a fine sand and used to make a variety of mortar bars ...

 · However, mortars use sand as the sole aggregate while concrete is made using aggregates much larger than sand. From the technical aspect, the strength and density of finished concrete depends on the distribution of the components. Usually the right proportions of different sizes of gravel and sand is used to create strong and dense concrete having extended life. As such, the aspect of cement ...

 · This aggregate actually consists of a mixture of various sizes of gravel and sand. In fact, cement is the most costly component present in concretes. When water is added to cement, a chemical reaction occurs, which results in hardening of the mixture. As such, concrete has identical composition to mortar. It is well known that the latter is extensively used in masonry work as a bonding medium ...
