Abstract EN

The use of a plastic as a partial replacementof coarse aggregate for the production of lightweight plastic concrete with varyingpercentages (25% ), (50%)and(75%)using plasticizer (SBR)with (2%)these mixture called lightweight plastic concretewhich compare with the reference mixture(A).At this search take (12)cubic samples ( 10 * 10 * 10 cm) which test in three age ( 7,14,28 )days , and (4) cylinders (10 * 30 cm) which test at 28 days it produced (12)ties with dimension(40*40*5) can test at ( 7,14,28 )days with modulus of rapture gives the results below which of :-(A)Cup ice samples of mixture (B) compressive strength (45 Mpa) compared the sample withreference mixture(A) (48.1 Mpa), next Mixture(C) nextMixture (D) with(28) days age.

Though the mixtures gives increase strength at later age which caring with water.(B)Cylindrical samples givesfor mix(B) tensile strength (3.6 Mpa) which compared with reference mixture(A) that give tensile strength (3.64)Mpa, next Mixture(C) next Mixture(D) at age (28)days then caring with water.(C) The ties samples gives (40*40*5)cm for mixture(B)with modulus rupture(4.05)mpa next mixture(C) then mixture(D) Compare with reference Mixture(A) = 4.15mpa which gives modulus rapture .That is refer the mixture(B) content optimum replacement of plastic, which give the better properties of concrete product.
