WITHDRAWN: Micro structural examination of low-density light weight concrete based on expanded polypropylene foam

Abstract

This research work focused on how sulphate resistance cement reacts with polypropylene foam on low density light weight concrete. It looked into the chemical resisting cement and physical properties of the low-density light weight concrete. Moreover, the research examined the behaviour of Recron 3S fibres in polypropylene foam aggregates light weight concrete. Considering that this research involved chemical processes, the methodology was also taken into consideration besides the mechanical tests and experimentation to validate the credibility of the results. In general, Low Density Light Weight Concrete has 300 to 800 Kg/ M 3 , high thermal conductivity nature, low handling costs, with many advantages including the dead load cutback of the building. When applied on the wall, flimsy concrete sustains its big abysses without making laitance coatings or films of cement. Nevertheless, appropriate ratio of water-cement is important in producing satisfactory cohesion between water and cement. Inadequate water can lead to lack of cohesion between particles, resulting to concrete strength loss. Similarly, excess water may lead to cement off aggregate, thereby forming laitance coatings which in turn weaken in solidity. This paper examines the micro structural analysis of the Low-density Light Weight Concrete based on the Polypropylene Foam Aggregates by replacing 100 percent of general aggregates. Procedures which focus on both Physical and Micro structural characters of the concrete are involved. In addition, the research is elaborated on fibres. The Implementation of these works is done by examining the concrete with Scanning Electric Microscopy (SEM) and X-ray Powder Diffraction (XRD). Further, this work is extended with Recron 3S fibres and then Exhibits the result.
