Natural fibres as construction materials

  This paper reviews the properties of different natural fibres. These natural fibres were investigated by different researchers as a construction material to be used in composites (such as cement paste, mortar and/or concrete). The different researches carried out and the conclusions drawn are briefly presented. The aim of this review is to compile the available data of different natural fibres evaluated in...

A refined formula for the allowable soil pressure using shear wave velocities

  Based on a variety of case histories of site investigations, including extensive bore hole data, laboratory testing and geophysical prospecting at more than 550 construction sites, an empirical formulation is proposed for the rapid determination of allowable bearing pressure of shallow foundations in soils and rocks. The proposed expression corroborates consistently with the results of the classical theory...

Forecasting the lowest cost and steel ratio of reinforced concrete simple beams using the neural network

  Given the compressive strength of concrete, yield strength of steel, span, dead and live loads, singly reinforced concrete simple beams are first optimally designed using genetic algorithms with constraints satisfying the specifications of the ACI code. The objective function is to minimize the total cost of tension steels, stirrups and concrete. A variety of beams are designed for the use of the neural...

Mechanical and hardening properties of accelerator on the cement concrete composites containing metallic reinforcements

  Research efforts in the past have been very successful in obtaining high strength concrete using various supplementary cementitious materials in concrete; however, the restriction on adding these mineral admixtures is primarily due to delayed reactivity with the hydration product of cement and the decelerated strength gain compared to plain cement concrete. Research efforts in the past have focused on the...

Simulation of the wire reverse bending test

  Steel wires are used for pre-stressing concrete structural units and for the construction of suspension bridges among other applications in civil engineering. The reverse bending and straightening of wires by rollers is employed as a routine quality check to detect laminations in wires. Experimental work on the reverse bending of wires and Finite Element (FE) simulation of bending of wires...
