Binder
A binder for screed compositions comprising calcium carbonate (CaCO3), neopentylglycol (NPG), a superplasticiser comprising one or more modified polycarboxylated ethers (PCE), a stabiliser comprising a high molecular weight synthetic polymer/powder, a curing agent, and 0.5-10 wt% of silicon dioxide (SiO2). The binder may comprise calcium carbonate, the curing agent and an adjuvant, wherein the adjuvant comprises calcium carbonate, neopentylglycol, superplasticiser, stabiliser, and silicon dioxide. The binder may further comprise calcium sulphate, which may be present in the adjuvant. The binder may be in powder form. The curing agent may comprise a fatty alcohol, with a chain length of C8-C22, and may comprise a carrier material comprising silica gel. The binder may be used in a screed or concrete, further comprising sand, cement and/or water. A screed comprising the binder, a concrete comprising the binder, and a method of forming a binder are also defined, wherein the method comprises combining and milling calcium carbonate, neopentylglycol, a plasticiser comprising one or more modified polycarboxylated ethers, a stabiliser comprising starch, a curing agent and silicon dioxide to form an adjuvant, and then combining with calcium carbonate to form a binder. Alternatively, the curing agent may be present separately from the adjuvant.
