Polymer Modified Concrete (P.M.C.) has been
discovered to be more potent than conventional cement
because of its excellent strength and raised perseverance, so
to enhance the performance, certain polymers are blended
in with concrete. The impact of Styrene Butadiene Rubber
(S.B.R.) over the compressive strengths, tensile strengths
and carbonation of cement has been examined in this
investigation, and the ideal polymer content for concrete
has additionally been resolved. This examination was
attempted to decide the impacts of polymer expansion on
compressive and tensile strengths utilizing concrete at
nearby ambient temperature with a consistent water-
cement proportion blend design. The mixes were prepared
with a 0 %, 5 %, 10 %, 15 % and 20 % cement-latex ratio of
Styrene-Butadiene Rubber. The fresh concrete slump test
was performed while the compressive and tensile strengths
were analyzed at various ages. S.B.R. latex has been
appeared to have an unfavourable effect at an early age,
even though applying S.B.R. latex to concrete at 28 days
brings about improved compressive and tensile strength.
However, In the current paper, workability, impact,
carbonation and acid resistance tests are performed.
