The mechanical properties of concrete with composition of scrapped rubber tyre crumb replacing part of the fine aggregates were investigated. The testing method of the mechanical properties was executed according to . Many groups of crumb rubber concrete specimens are manufactured in different kinds of size and amount of rubber chips. The powder rubber and crumb rubber were mixed into C35 plain concrete, by the volume rations of 0%, 20%, 40 %, 60%, 80% and 100% of the fine aggregates, to investigate the influence of size and amount of rubber chips on the mechanical properties. The results of test indicate: the cubic compression strength, the tensile splitting strength and the strength of rupture decreased with the increase of rubber admixture. But there are some remarkable properties which is difficult to attain on ordinary concrete, such as better cracking resistance, better deformation property, minor density and so on.

The cementitiousness between rubber particles and cement-based material could be raised because of the surface modification of rubber,thus enhance the mechanical property of crumb rubber concrete and improve the interface effect of rubber particles.We had researched the change regulation about the ratio of bending-compressive strength of the crumb rubber concrete modified by latex,the concrete with various quantity of rubber,under the condition dosage of latex is 0.5% of cement quality.The result of experimental prove that,compressive strength, splitting tensile and flexural strength could be enhanced because of latex injecting,and the ratio of bending-compressive strength could be enhanced at the same time.

This article presents experimental study performed on a first-of-its-kind frame fabricated using crumb rubber concrete, that is, concrete with waste rubbers (crumb) as a partial replacement of fine aggregate (sand). A 20% volume of sand was replaced by rubber crumb. Free vibration and shake-table tests were performed on 1:3 reduced scale frame models, both conventional reinforced concrete frame and crumb rubber concrete frame. The dynamic properties (i.e. frequency/time period, elastic viscous damping, and floor acceleration amplification) and seismic response parameters (i.e. ductility and response modification factors) were obtained. In addition, lateral displacement demand was correlated with peak base acceleration to derive seismic response curves. The seismic performance of crumb rubber concrete frame was compared with the conventional reinforced concrete frame in order to assess the feasibility of rubberized concrete for building constructions in areas of active seismicity. The following were concluded on the basis of experimental study: the elastic damping reduced by 12%, the initial time period increased by 6%, specific weight of concrete reduced by 6%, maximum lateral load reduced by 20%, lateral maximum story drift capacity increased by 30%, displacement ductility ratio increased by 2%, response modification factor reduced by 24%, maximum peak base acceleration resistance corresponding the incipient collapse state increased by 40%.
