Light Weight Aggregate

Compressive performance test of lightweight aggregate concrete with different quantity of steel fiber and plastics-steel fiber is carried out, and the following conclusions are obtained. It is not obvious that the change of compressive strength when LC30 light weight aggregate concrete mixed with plastics-steel fiber. Compressive strength is enhanced steadily to light weight aggregate concrete with steel fiber, but the amplitude is not large. The compressive deformation and failure characteristic of lightweight aggregate concrete are greatly improved as a result of mixed with plastics-steel fiber and steel fiber, and the failure pattern of lightweight aggregate concrete changed from brittle failure into a certain plastic failure.

Fibre Fraction

In this study, lightweight aggregate concrete (LWAC) specimens with different plastics-steel fibre volumes were tested to investigate the effect of plastics-steel fibre fraction on the mechanical properties of LWAC through the experimental research and theoretical analysis. The experimental results indicated that incorporation of steel fibre into LWAC can greatly improve such mechanical properties as flexural toughness and impact resistance, but leads to a little effect on compressive strength and flexural strength.

Aggregate Concrete

Lightweight aggregate concrete has lower density and lower elasticity modulus, so it has better earthquake resistance. But the low strength limited the application of lightweight concrete. Steel fiber can improve the strength of lightweight aggregate concrete. In this paper, the influences of different lengths of steel fiber on the slump, compressive strength, splitting tensile strength and antiflex cracking strength are investigated. The results show that adding steel fiber reduces the workability of the concrete mixture, but it improved the each strength of light weight concrete and different lengths have the different regularity of effects.

Light Weight Aggregate

Referring to an egg shaped yield function for geotechnical materials, a failure criterion for light-weight aggregate concrete is put forward, in which the tensile and compressive meridians are egg shaped curves and the failure envelopes in deviated plane is smooth elliptic curves. The suggested failure criteria could describe the failure characteristic of lightweight aggregate concrete at different stress state. The precision of the suggested egg shaped failure criteria is verified by comparing with experiment data of lightweight aggregate concrete.

Light Weight Aggregate

This research deals with production of light weight aggregate concrete by using clayey stone aggregate, normal material (cement , sand) and some of mineral admixtures (fly ash and steel fiber ). Many trial mix were doing some of these by weighing ratio and others by volumetric ratio . We get light weight aggregate concrete (LWAC) with 24.92 N/ mm2 compressive strength and we improved mechanical properties by adding same percentage of fly ash and steel fiber (0.5 ,1 ,1.5) % of each other as a percentage weighing ratio of cement content . compressive strength increased with (7.8 , 5.2 , 2.9) % , splitting tensile strength increased with (20 ,16.71, 12)% and flexural strength increased with (24.5 , 17.9 , 8) % when adding (0.5 ,1 ,1.5) % of each steel fiber and fly ash respectively. The practical results of the current study indicates that the using clayey stone to produce (LWAC) is success and we can improved mechanical properties of this (LWAC) was produced in this research by adding fly ash and steel fiber with previously percentage.

The Impact

The article studies the impact of steel fiber on the performance of lightweight aggregate concrete,including compressive strength, flexural strength, modulus of elasticity and impact toughness. The experimental studies show that steel fiber has little effect on the compressive strength of lightweight aggregate concrete, however, it can improve the pattern obviously. With the increasing of steel fiber content, the flexural strength and impact toughness of concrete increases. With the increasing of steel fiber content ,the elastic modulus of concrete also increases. The studies of this paper provide a certain technical references with the future research of steel fiber reinforced lightweight aggregate concrete.

Fiber Types

In this study, the effects of fiber types on the mechanical properties of lightweight aggregate concretes were investigated. Three types of fibers, namely, polypropylene fiber, steel fiber and water hyacinth (Eichhornia crassipes) fiber, and two types of lightweight aggregates, namely, expanded polystyrene and ceramsite were used. The compressive strength and splitting tensile strength of concretes were tested. The results show that both the compressive strength and the splitting tensile strength were improved by adding a reasonable volume of steel fiber and polypropylene fiber into LWAC. The addition of water hyacinth fiber had little effect on the compressive strength of LWAC, while a little increase was observed in the splitting tensile strength.
