Influence of non-hydrocarbon substances on the compressive strength of natural 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...

Six selected clonal latexes were chemically analyzed for thirteen compositional parameters each.
