Concrete Producing Materials

Concrete - Wikipedia

Mayan concrete at the ruins of Uxmal is referenced in Incidents of Travel in the Yucatán by John L. Stephens. "The roof is flat and had been covered with cement". "The floors were cement, in some places hard, but, by long exposure, broken, and now crumbling under the feet." "But throughout the wall was solid, and consisting of large stones imbedded in mortar, almost as hard as rock." Small-scale production of concrete-like materials was pioneered by the Nabateantraders who occupied …

Concrete Production - an overview | ScienceDirect Topics

Concrete production is now, of course, a mature technology. The ancient Greeks and Romans both produced mortars that may be considered to be the forerunners of today’s concretes, while “modern” concretes have been in use since the middle of the 19th century. These concretes now constitute a highly sophisticated family of materials.

Materials and Methods for High Performance Concrete

Material technology has evolved concrete today into an engineered material with several new constituents. The concrete today is tailor made for specific applications and it contains several different materials like PFA, GGBSF, Microsilica, Metakaolin, Colloidal Silica and several other Binders, Fillers and Pozzolanic materials.

Types of Pozzolanic Materials | Admixtures | Concrete ...

Pozzolanic materials are siliceous and aluminous materials, possessing little or no cementitious value by themselves, but in finely divided form and in the presence of moisture react chemically with calcium hydroxide liberated on hydration of cement at ordinary temperature to form compounds, possessing cementitious properties.

Raw materials - Cement

Raw materials are extracted from the quarry, then crushed and ground as necessary to provide a fine material for blending. Most of the material is usually ground finer than 90 microns - the fineness is often expressed in terms of the percentage retained on a 90 micron sieve.
