For the relationship three R2 is equal to 0.89 and R2 is 0.96 for relationship four. 1.2 1 0.8 0.6 0.4 0.2 0 Experimental data of concrete Experimental data of mortar Poly.

It can be observed that all concrete mixes showed a strength of splitting tensile was reduce with raise volume of LDPE aggregate. The concrete tensile splitting strength is highly affected by interfacial transition zone (ITZ)characteristics; when the carriage attains its maximum value the possibility of engage amide LDPE particles on cracked surfaces decline because of short cylinder form of LDPE particles and its elasticity, reduce flexible modulus of granules of LDPE than that of the cement paste and internal bleed water from normal aggregates that surrounded and amassed the waste LDPE granules .In general, specimens consist of LDPE aggregates splitting fail do not reveal typical Relative compressive strengthPDF Image | Properties of Concrete and Mortar with LDPE Aggregate
