The invention relates to a composition for making flooring material comprising resin and particles comprising ammonium quaternary salt. The resin is generally an unsaturated polyester resin. The flooring materials, or engineered stone slabs from which the flooring materials or other material can be formed, are generally made from combining the resin, particles, inorganic particulate material and an initiator and allowing the resin to cure. The flooring material composition may be cobalt free. Metal catalysts may be used to cure the resin.

Inorganic polymer/organic polymer composites and methods for their preparation are described herein. The inorganic polymer/organic polymer composites comprise a first layer comprising an inorganic polymer and a second layer adhered to the first layer comprising an organic polymer. The inorganic polymer is formed by reacting, in the presence of water, a reactive powder, an activator, and optionally a retardant. The reactive powder comprises 85% by weight or greater fly ash and less than 10% by weight portland cement. Also described herein are building materials including the composites.

The present invention is directed to a biopolymer cement additive, a biopolymer cement composition containing the additive, the use of the additive for the production of, mortar or concrete and a process for the preparation of concrete or mortar implementing the biopolymer cement additive.

A red mud utilization method based on co-processing of industrial exhaust gas, sewage treatment and an environment-friendly and high-performance civil functional material, belongs to the technical field of environmental science and cementitious material preparation, and relates to a preparation process of a solid waste-based cementitious material, specifically including the steps: preparing an environment-friendly and high-performance red mud-based civil functional material by using slag obtained after sewage treatment with red mud and other solid wastes in physical and chemical activation and high-temperature calcination methods. The compressive strength of a solid waste-based cementitious material prepared by using the method can reach 29 MPa, the leaching quantity (lower than 3.0 ppm) of toxic elements such as heavy metals is far lower than the national standard requirement, and a solid waste-based cementitious material with great performance can be prepared.

The present invention relates to a silicone composition, a substrate, such as cement, coated with the silicone composition, together with a process for providing a cross-linked silicone coated substrate, the silicone composition comprising at least: (A) an organopolysiloxane comprising an organocyclosiloxane; (B) an organosilane comprising at least two cross-blinking groups, X; and (C) an organosilicone resin comprising at least two cross-linking groups, X; wherein at least one of the organosilane (B) and the organosilicone resin (C) comprises at least three cross-linking groups.
