Casting and curing of concrete cylinder and beam specimens from representative samples of fresh concrete is crucial in building constructions. This is because the results of the tests conducted on
Compounds in cement mainly are tricalcium silicate, dicalcium silicate, tricalcium aluminate, and tetracalcium alumino ferrite. Not only do these compounds control most of cement properties but als
Precast concrete is prepared by casting concrete in reusable molds or “form” which is then treated in a controlled environment, conveyed to the construction site, and lifted to the place. The
REACTIVE POWDER CONCRETE COMPOSITION & MANUFACTURING: Reactive powder concrete has been developed to have a strength of 200 to 800 Mpa with required ductility. It is new technique involved in t
Swimming pools are constructed with concrete as a material for residential as well as hotels, clubs and schools. The concrete material has proved to be one of the long-life material that is best suited for this construction. The basic requirements for swimming pool construction are: It is necessary to have a pool shell i.e. 1.
A request for quote or a quotation (RFQ) in a construction project is an invitation to contractors for bidding procedure of various activities of project by owner or main contractor. Request for quote can be for construction works, supply of materials or services in a construction project. This can be explained by an example: If
Working space is the additional space provided between the edge of the excavation and the footing for the ease of labor movement for fixing, removing shuttering boards, pouring of concrete, and com
Civil Engineers are known to test the limits of building structures, by going higher, longer or lighter. On the other hand Civil Engineers are by definition very conservative. These two professiona
The concrete is manufactured using cement, sand, gravel and water as the main components materials. The active material in concrete is cement which binds other materials physically and chemically w
The use of renewable energy is a great way to minimize or eliminate emissions from construction sites. Construction sites are the major sources of greenhouse gas (GHG) emissions, and they are responsible for around 39% of all energy and procedure-related carbon dioxide release worldwide. For instance, construction equipment in the United States consume around 6
