1. Concrete What it is:a mix of cement, aggregate, and water. Uses: Traditionally used for supports, walls, floors, and exterior structures like driveways or patios, concrete is growing very popular in home construction for such diverse purposes as countertops and fencing. It is durable and ...
In general this type of work does not require a vast knowledge ofconcrete pouringand placing. Tools used are often small hand tools, mops, sprayers and tape and preparation materials. Often does not require heavy lifting nor the use of aggressive machinery. Can be started small and grow with...
In this study a many mixes of concrete was produced by using the materials which are available locally. A full gradient of course aggregate was used. Three main types of mixes were made in addition to reference mix. First mix depended on absence sand from the parameters in the second mix ...
