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...

Rapid increase in construction activities leads to active shortage of conventional construction materials due to various regions. Concrete is most widely used construction material. Cement, sand & granite stone are the constituents of the concrete. Researches were researching for cheaper materials that can be used as substitute for these materials. In this context an experimental study was carr...

Self-compacting concrete is an innovative technology with higher flowability properties by adding the mineral admixtures such as superplasticizers and not necessary to vibrate concrete. The banana fibers were used in this investigation because fiber environmentally friendly material good compared synthetic fiber. experimental test consisted of two phases research, i.e., preliminary which had ai...

The results of experimental investigations on the study of concrete with partial replacement of cement are presented in this paper. The concrete grade of M30 has been selected and designed as per Indian Standard method. The specimens based on control mix have been cast without fly ash and silica fume. Cement was replaced by 0%, 10%, 20%, 30%, 40%, 50% and 60% of fly ash by the weight. 20 % of s...

Self-compacting Concrete is one of the new innovative types concrete, and it used widely in construction several industries. This type concrete can be made by using different admixtures their combinations. The main aim SCC to improve durability structure also improves workability structure. Nowadays large structures, isn't easy compact reinforced without voids. overcome self-compacting concrete...

Abstract In this research article effect of steel fibers on workability and compressive strength recycled aggregate concrete is presented. Recycled aggregates from demolished waste were used in equal proportion with conventional aggregates. Steel 1 mm diameter 25 length used. For preparation 1:2:4 mix 0.55 water-cement ratio was Workability each checked by slump cone test. Total 40 samples prep...

Joint connection methods, such as shear key and loop bar, improve the structural performance of precast concrete structures; consequently, there is usually decreased workability or constructional efficiency. This paper proposes a high-efficiency skewed pipe shear connector. To resist shear and pull-out forces, the proposed connectors are placed diagonally between precast concrete segments and a...

Today concrete is most widely used construction material due to its good compressive strengt h and durability. Depending upon the nature of work the cement, fine aggregate, coarse aggregate and water are mixed in specific proportions to produce plain concrete. Plain concrete needs congenial atmosphere by providing moisture for a minimum period of 28 days for good hydration and to attain desired...
