Ingredients for concrete are cement‚ fine aggregate‚ coarse aggregate and water. The best concrete can be obtained by mixing the ingredients in correct proportions. The ideal proportion of concrete will be that‚ which produces greatest strength and solidity at the least cost. In estimating the quantities of ingredients for cement concrete it should keep in mind that voids of coarse aggregates are filled up by sand and voids of fine aggregates are filled up by cement. The concrete mix of 1: 1: 2 and

How do concrete and steel compare in the construction of large commercial buildings? Office buildings‚ Hotels‚ Sports Complexes‚ and other buildings have the purpose of bringing people inside. The goal is to keep occupants comfortable and safe‚ while keeping the cost associated withe the construction and maintenance of the building low. Both materials have advantages and disadvantages. However‚ when it comes right to it‚ the differences between the tow materials balance themselves out . There is

Concrete mixer which is also commonly named as cement mixer is a device that homogeneously combines cement‚ aggregate such as sand or gravel‚ and water to form concrete. History Why did man invent concrete mixer? The reason of it is that in the early 20th century‚ the concrete was developed when some new materials added to cement. After the concrete was developed‚ the art of mixing it had to reform. Therefore‚ concrete mixers were becoming pretty popular by early 20th Century. This coincided

Concrete is a composite product obtained artificially by hardening of mixture of cement‚ sand‚ gravel and water in pre-determined proportions. When these ingredients are mixed‚ they form a plastic mass which can be moulded in desired shape. It gets hardened into hard solid mass. Water is one of the important ingredients of concrete. This is required not only for chemical reaction‚ but also for curing purposes. The chemical reaction of cement and water‚ in the mix‚ is relatively slow and requires

Title : Concrete Cube Compressive Strength (7 days) Introduction : To determine the strength‚ maximum load can be applied and workability of concrete mixture. Theory : Hard concrete test were conducted at the age of 3‚ 7‚ 14‚ 21 and 28 days after curing(but we tested it for 7 days only). The concrete strength increases according to the age‚the mixture of its concrete design and the strength increment will continue for sometimes. Nevertheless‚ for most of the work‚ the concrete strength on
