A proposal is made for a cementitious system which comprises accelerator particles coated with crosslinked shellac, for the use as an additive component which comprises the accelerator particles coated with crosslinked shellac, and for a cement slurry which comprises the cementitious system and water.

Cementitious system comprising accelerator particles coated with crosslinked shellac

A novel binder system comprising at least one latent hydraulic binder, at least one amorphous silica, optionally at least one reactive filler and at least one alkali metal silicate is proposed. It was surprisingly found that the binder system according to the invention hardens in the form of a hybrid matrix which is acid-resistant, water-resistant and alkali-resistant. The binder system can be used for the production of a hydraulically setting mortar which, after setting, hardening for seven days and subsequent storage for three days in acid, base and/or water, has compressive strengths of more than 15 N mm, preferably more than 20 N mmand in particular more than 25 N mm, according to DIN EN 13888.

Inorganic binder system for the production of chemically resistant construction chemistry products

The use of a mixture of at least one polyol and at least one cyclohexanepolycarboxylic acid derivative for reducing or minimizing the dust emission when handling pulverulent construction chemistry products, processes for the preparation of the pulverulent construction chemistry products and hydraulically setting materials containing the mixture according to the invention are proposed.

Use of polyols and cyclohexane polycarboxylic acid derivatives for the removal of dust from chemical construction products

The present invention relates to building material mixtures which contain slag sand and zinc salts which have from 0 to 8 carbon atoms in their structure. The invention furthermore relates to the use of zinc salts for preventing discolorations during the hardening of the building material mixtures.
