Concrete had been used in many decades due to its properties and economics. but, it has some barriers together with low failure pressure, low flexural and tensile strength, low chemical resistance, and and so forth. there are many solutions for doing away with its predicament. The most commonplace in production is using metal reinforcement for enhancing flexural and tensile strength [1] . studies have been accomplished by way of using titanium alloy for metallic reinforcement machine in aiming of earthquake resistant constructing [2] . the opposite solution changed into high performance concrete utility [3] . The excessive performance concrete is produced by means of low water/cement ratio, adding admixture, additive and and so forth. So, excessive overall performance concrete will need greater cement and high-priced. additionally high performance concrete might be brittle, and greater inclined for cracking [4] .The polymer addition into concrete aggregate might be used for casting off concrete drawback. The polymers in concrete were used in many a long time for widen the concrete packages. The polymer in concrete can be functioned as binder both without or with cement in shape of polymer modified concrete, polymer concrete or polymer reinforcement concrete, or filler. Polymer as binder would improve the interfacial area, and polymer as filler could fill the void. So it would end result low porosity concrete [5] . The polymers for concrete components are varied, which include elastomer (natural rubber, synthetic rubber), thermoplastic (PVA, styrene-acrylic, and so on.), thermoset (epoxy), bituminous (tar, asphalt) and latex change [6] . and that they have been researched for plenty concrete applications.
The herbal rubber have been researched for improving the concrete electricity [7] and sturdiness in intense environment [8] . For artificial rubber, the most utilized in construction is Styrene Butadiene Rubber. Researches were accomplished with the aid of interacting SBR with silica fume for enhancing of interfacial region [9] , its impact in concrete into microstructure and chloride permeability [10] and its impact as admixture in high Polymer Modified performance concrete [11] . the other polymer utilized in creation is epoxy. research of epoxy were finished for improving concrete durability [12] , its effect to microstructure [13] and fire resistant [14] .
The polymer addition into concrete aggregate might be used for enhancing the earthquake resistant and damping capacity. The styrene Butadiene Rubber (SBR) have been studies for that reason with the aid of evaluating of power dissipation of concrete [15] . additionally, rubber in form of crumb rubber have been studies for improving the strength dissipation [16] and static and dynamic properties [17] .
Indonesia is 2d biggest producer herbal rubber within the international. The rubber is exported as herbal rubber, approximately eighty% [18] . which will get delivered price of rubber, research have been achieved of change of natural rubber (latex form) into copolymer [19] . The modified latex have been studies for improving strength and durability of concrete [20] , its impact into fire resistant homes [21] and earthquake resistance [22] . The Researches of copolymer of natural latex changed concrete used ordinary Portland cement as binder.
there is a new trend of Indonesian cement enterprise, by lowering the manufacturing of ordinary Portland cement and greater production extent in combined cement production, as a dedication to Kyoto protocol for CO2 lowering. So, this research turned into advanced by means of replacing the normal Portland cement into mixed cement in generating polymer modified concrete. The blended cement was composing of min sixty five% clinker and max 35% supplementary cementitious substances together with fly ash, trass/herbal pozzolan, and lime. The supplementary cementitious substances had been used for enhancing concrete sturdiness with the aid of forming additional CSH [23] and generating sustainable concrete. the usage of supplementary cementitious materials may want to reduce the CO2 emission and to be environmental pleasant in cement production [24] .
besides the usage of blended cement, this research become handling changed herbal latex as concrete components. The polymers are copolymer of natural latex methacrylate (KOLAM) and copolymer of herbal latex styrene (KOLAS). The polymer modified concrete of blended cement and copolymer of natural latex have been evaluated for static and dynamic analysis. The static houses are compressive power, flexural strength, splitting tensile strength and modulus of elasticity. The static residences had been evaluates as a base of concrete energy assessment. based totally on the static properties, research turned into evolved into dynamic evaluation. The dynamic assessment changed into achieved primarily based on impact load and energy dissipation profiles. The dynamic assessment might be used as a preliminary studies for concrete with impacting resistant (desirable damping capacity) and earthquake resistant utility. So, by means of polymer addition will widen concrete utility.
The worried mixed cement and copolymer of herbal latex could be used as animproving concrete overall performance in greater sustainable. because of combined cement extra sustainable than regular Portland cement and copolymer of herbal latex is renewable cloth. hence, the studies could be used as a reference in inexperienced construction for designing of effect and earthquake resistant constructing.
