Experimental Study of Crumb Rubber in Concrete
Crumb rubber is a material produced by shredding and commutating used tires. Waste tire dumping, disposal of these materials or burning these tires cause serious health and environmental problems. On the other side the traffic intensity also increasing day by day and thus bearing capacities also increased the long term goal of the work is to find a means to dispose of the crumb rubber in concre...
متن کاملBond of High Strength Concrete with High Strength Reinforcing Steel
This paper presents a study about the bond of high strength concrete with high strength steel. Fourteen pull out tests were carried out to determine the bond. The concrete strength was about 70 MPa and the steel was a 500 MPa grade. Bar diameters used were 12, 16, 20, 25, 28, 32 and 36 mm. In order to investigate the effect of cover, each test was done twice, once in a 240 mm diameter concrete ...
متن کاملConcrete with Crumb Rubber from Used Tyres
This study aims to determine the influence of the substitution of a variable volume of aggregates on a concrete by an equivalent quantity of crumb rubber (CR) obtained from used tyres. The physical and mechanical properties of different concretes, which were developed through laboratory tests, have been studied for this goal. The experimental method employed is based on the production of a refe...
متن کاملCorrosion of Reinforcing Bars in Concrete
The causes and mechanisms of corrosion of reinforcing bars in concrete are described in terms of the practical issues as well as the electrochemistry. The parameters affecting corrosion are (i) the ingress of aggressive species, such as chlorides, which break down the protective film on the reinforcing bar and (ii) the amount of those species necessary to do so. The former is largely controlled...
متن کاملPromoting the use of crumb rubber concrete in developing countries.
The use of accumulated waste materials in third world countries is still in its early phases. It will take courage for contractors and others in the construction industry to recycle selected types of waste materials in the concrete mixes. This paper addresses the recycling of rubber tires accumulated every year in Jordan to be used in concrete mixes. The main objectives of this research were to...
