In this article, the author introduces tests and application examples of short columns by outer\|packing stick steel with high\|strength gelatinization concrete.

Cracking-resistance and flexural property of rubberized concrete;

Experimental Study on Deformation Characteristic of Elastic Rubberized Concrete Under Compressive and Flecxural Loading;

Experimental study on brittleness of rubberized concrete;

Uniaxial compressive experiment for crumb rubber concrete(CRC) was conducted.

A grey prediction model of drying shrinkage of crumb rubber concrete(CRC) is established based on GM(1,1).

In order to effectively alleviate the increasingly serious environment problem of waste rubbers,an advice of adding the recycled ground rubbers into concrete to produce the rubcrete was put forward which aimed at change of the waste rubbers from the black rubbish and hazards of environment into green resource.

At present, the material property and applied technology of rubber modified asphalt concrete are studied and developed widely at home and abroad, but the study on rubcrete is only at the beginning stage in China.

At the same time, a new type of pavement-layer-steel fiber reinforced rubber concrete pavement is introduced by using a layer-steel fiber reinforced pavement structure.

Combining thermal diffusivity and coefficient of linear thermal expansion test,the thermal performance differences of five different dosage(0,60,120,180,240 kg/m3) rubber concrete were study.

Rubber-filled concrete was made by using worn-out rubber tyres to substitute for a certain proportion of sands aiming at improving the anti-cracking performance and endurance of concrete used in road.
