The matrix is the monolithic material into which the reinforcement is embedded, and is completely continuous. Metal Matrix Composites (MMCs) possess significantly improved properties. Among the MMC's aluminium composites are predominant in use due to their low weight and high strength. In this project the Tensile test, compression and Hardness test results of Aluminium 6061 Reinforced with E-Glass Fibre and Fly ash composite is studied. Also microstructure of the specimen is analysed. The reinforced composites were manufactured by Stir Casting process. Each fabrication carries the E-glass reinforcement content varied from 0% to 6% with incremental steps of 2% and Fly ash of 0% to 15% with incremental steps of 5%. The casted composite specimens are prepared according to ASTM standards by facing and turning operations to conduct tensile, hardness and compressive test. Microstructure of the composites was observed to study the bonding of E-Glass and Fly ash with AL6061. Mechanical tests were carried out on specimens from each composition and it is observed that reinforcement enhances the mechanical properties of Aluminium 6061 Composites.

Porous concrete has its application in many fields. Mainly for drainage purpose porous concrete can be used as a covering as well as to drain the liquid. Strength is only drawback in the porous concrete as the surface area contact between the coarse aggregates is less. In order to enhance the strength properties, poly propylene was used in layers. Various no of layers was introduced in the prism as well as for cube to determine the strength enhancement properties. Through experimental study it was found that strength due compressive force of the pervious concrete increases up to placing 3 layers of polypropylene geo textile fabric and get decreased after that. Similar to the compression test, the flexural strength also showed similar behaviour in the increase in strength up to the 3no of layers. Similarly, porosity test was carried to find the effect of porosity due to PP layers. It was found that 18.5% reduction in porosity was noted when 3 layers of PP were incorporated.
