2019-5-25  For a natural carbonation process, diffusion of CO2 into the pores of the cement paste is considered as the rate-controlling step. Instead, the accelerated reaction kinetics of calcium carbonate precipitation in the supercritical process was chemically controlled by the detachment of calcium ions from solid portlandite or CSH gel.

Partial Replacement of Portland-Composite Cement

The use of biomass fly ash from fluidized bed combustion as a cement replacement material could be a promising method for both minimizing the amount of landfilled fly ash and reducing CO 2 emissions in the concrete and cement industry. In this study, fly ash from fluidized bed combustion of peat and forest industry residue was used as a supplementary cementitious material for portland-composite cement

Properties of 3D-printed fiber-reinforced Portland

First insights into a 3D-printed composite of Portland cement paste and reinforcing short fibers (carbon, glass and basalt fibers, 3–6 mm) are presented, resulting in novel materials that exhibit high flexural (up to 30 MPa) and compressive strength (up to 80 MPa). Alignment of the fibers, caused by the 3D-printing process is observed, opening up

What is the difference between Portland and

2016-3-8  In civil engineering Portland cement is a complex of umhydrated calcium and aluminium silicates produced by the roasting together of limestone and clay. The limestone was originally obtained from Portland in Dorset when patented in the 19th century to replace quicklime. When mixed with fly ash or ground slag, by products of coal-fire power stations or smelting the composite materia is formed

CEMENT RAW MATERIALS International Cement Review

2013-6-9  Portland cement is the most widely produced cement, both in the UK and worldwide. The term ‘Portland cement’ was created by its inventor in 1824 because of the presumed resemblance of the set material to Portland Stone, the well-known natural building stone.
