Although concrete typically begins its life at a highly basic pH of about 13, the pH values at exposed surfaces soon fall as reactions occur between carbon dioxide from the atmosphere and alkalis in the concrete— a process known as carbonation. Over time, fronts of carbonated concrete, with pH values of about, advance below exposed surfaces.
Ultrahigh performance concrete (UHPC) is an advanced construction material that affords new opportunities for the future of the highway infrastructure. The Federal Highway Administration has been engaged in research on the optimal uses of UHPC in the highway bridge infrastructure since 2001 through its Bridge of the Future initiative.
Download Advanced Concrete Technology Constituent Materials By John Newman – The book is based on the syllabus and learning objectives devised by the Institute of Concrete Technology for the Advanced Concrete Technology (ACT) course. The first ACT course was held in 1968 at the Fulmer Grange Training Centre of the Cement and Concrete Association (now the British Cement Association).

Civil Concrete Technology Lectures Notes Concrete Definition In its simplest form, concrete is a mixture of paste and aggregates (rocks). The paste, composed essentially of portland cement and water, coats the surface of the fine (small) and coarse (larger) aggregates. Through a series of chemical reactions called hydration, the paste hardens and gains strength to form the rocklike mass known ...
