Cement concrete is an important construction material. Its importance is increasing every day. It is a composite material consisting of a binding material, which is essentially cement, inert mineral Filler, known as aggregates and water. Thus cement concrete can be prepared by mixing above ingredients in a fixed proportion. Green concrete is a plastic mass, …
Technologies are becoming increasingly complicated and increasingly interconnected. Cars, airplanes, medical devices, financial transactions, and electricity systems all rely on more computer software than they ever have before, making them seem both harder to understand and, in some cases, harder to control. Government and …

Cement Manufacturing—Technology, Practice, and Development 4.1 Introduction The history of cement goes back to Roman Empire. The credit of the invention of the Portland cement was first produced by a British stone mason, Joseph Aspdin of Leeds, Yorkshire, England. A patent was approved to him for a material produced
Cementation of nuclear wastes is a mature and reliable technology used to immobilise different waste types. Cementitious wasteforms are briefly discussed with focus on their containment performance.
Findings. The results show that a total of 26 technologies were identified from the literature, and these can be categorised into five groups in terms of their functionality in construction process, namely: (1) data acquisition, (2) analytics, (3) visualisation, (4) communication and (5) design and construction automation.
Technology has impacted almost every aspect of life today, and education is no exception. Or is it? In some ways, education seems much the same as it has been for many years. A 14th century illustration by Laurentius de Voltolina depicts a university lecture in medieval Italy. The scene is easily recognizable because of its parallels to the …
