Influence of non-hydrocarbon substances on the compressive strength of rural rubber latex-modified concrete

Inclusion of polymeric substances into hydraulic cement concrete has made a tremendous impact towards improving its performance properties. However, polymers to be included into concrete should neither cause damage to its mechanical capacities nor to its durability characteristics. This article repo...
