The invention concerns a method for fluidifying wet concrete or industrial mortar compositions comprising: (a) at least one hydraulic binder, (b) at least one water reducing polymer, (c) at least one accelerator in the form of a salt containing at least one kosmotropic ion, (d) water, and (e) possibly one or more supplementary cementitious materials, and (f) possibly one or more filler materials, the method comprising a step of adding at least one salt (ch) including at least one chaotropic ion to the concrete or industrial mortar composition.

Provided herein are compositions, methods, and systems related to aggregates, such as e.g., lightweight aggregates, formed from the reactive vaterite cement compositions.

The present invention provides calcium sulphate-based product having reduced shrinkage after exposure to high temperatures, the product comprising gypsum, a pozzolan source (e.g. in an amount between 4-27 wt %) and a metal salt additive (in an amount between 0.5 and 10 wt %). The pozzolan source may be selected from a kaolinitic clay material, fly ash, rice husk ash, diatomaceous earths, volcanic ashes and pumices, micro-silica, silica fume and silicone oil. The metal salt additive may be a metal salt which decomposes between a temperature of 300-500° C. to yield a metal oxide, e.g. magnesium nitrate.

An anti-explosion flooring material is disclosed. The material is prepared by foaming, modification and rust prevention treatment of an iron alloy material and other auxiliary materials having components in percentage by weight: 85% of iron, 8% of manganese, 6% of silicon, and the rest amount of carbon. Because a foaming agent and rare earth are added, the static conducting performance of the flooring material is improved.

The present invention relates to an additive for hydraulically setting compositions, comprising a colloidally disperse preparation of at least one salt of a mono- or polyvalent metal cation and of at least one compound which is able to release an anion which forms a low-solubility salt with the metal cation, and of at least one polymeric sulphonated dispersant. The additive is suitable particularly as a slump retainer.

The present invention provides a calcium sulphate-based product (e.g. a wall board) comprising gypsum, a pozzolan source such as a clay additive, rice husk ash or diatomaceous earth and a metal salt additive. The product may be produced by drying an aqueous slurry comprising calcined gypsum, the pozzolan source and the metal salt additive. The clay additive may be a kaolinitic clay. The metal salt additive may be a magnesium salt e.g. magnesium nitrate, magnesium chloride or magnesium hydroxide.
