As indicated by Bied (1922), [2] who was the inventor of this type of cement, the terms "Ciment fondu" ("fused cement") and "Ciment électro-fondu" ("electro-fused cement") refer only to the manufacturing process involving the melting of the base materials (CaO obtained after the decarbonation of CaCO 3, and Al 2 O 3).
This template has been created for transclusion in the articles Concrete, Cement, and Silica fume. It replaces the file at right. That file had been tagged for translation to SVG format, as if it were a graphic. But since it is really a table, I have re-rendered it in wiki markup.
Fondu Fyre is a heat and erosion resistant concrete developed during the Apollo space program. It was developed to withstand the supersonic plume of a rocket engine during launch and hot-fire tests [citation needed]. Allied Mineral Products based in Ohio holds the registered trademark on the name Fondu Fyre. [1]

Deep cement mixing consists of using specially designed equipment, such as augers or mixing paddles, to mechanically mix the soil with an in-situ binder. The process simultaneously breaks up the soil without removing it, injects a binder at low pressure and thoroughly mixes the binder with the soil to form a reinforced block of soil after ...
Volumetric concrete mixers can produce exactly the amount of concrete needed when it is needed at any time. [1] Some concrete suppliers offer general purpose concrete batched in a volumetric mixer as a practical alternative to ready-mix if quantities and schedules are not fully known, to eliminate waste and prevent premature stiffening of the mix.
A higher ratio gives a too fluid concrete mix resulting in a too porous hardened concrete of poor quality. Often, the concept also refers to the ratio of water to cementitious materials, w/cm. Cementitious materials include cement and supplementary cementitious materials such as ground granulated blast-furnace slag (GGBFS), fly ash (FA), silica ...
GGBS cement can be added to concrete in the concrete manufacturer's batching plant, along with Portland cement, aggregates and water. The normal ratios of aggregates and water to cementitious material in the mix remain unchanged. GGBS is used as a direct replacement for Portland cement, on a one-to-one basis by weight.
