Sulphoaluminate cement Sulphoaluminate cement is a kind of special cement invented by China. It is a kind of hydraulic cementing materials which main mineral contents are anhydrous calcium sulphoaluminate and β-calcium silicate, made from raw materials like limestone, alumina and gypsum, through high temperature calcinations which is usually under 1300-1350 °C, adding different proportions … Continue reading
Aluminate Cement Aluminate cement, product code as CA, also known as high alumina cement, is made from bauxite or limestone through melting or sintering. It is a hydraulic binder which mainly contains fine monocalcium aluminate and dicalcium aluminate. If necessary, it is also possible to add an appropriate amount of α-Al2O3 powder in grinding cement … Continue reading
In Chinese GB 175-2007 Standard, general purpose portland cement is defined as hydraulic cementitious material made of Portland cement clinker and appropriate amount of gypsum and specified mixed materials. According to the variety and dosage of its mixed materials, it is divided into Portland cement, ordinary Portland cement, slag Portland cement, pozzolanic Portland cement and … Continue reading
Fineness of Cellulose Ether Fineness is also an important performance indicator for cellulose ether. The Hydroxypropyl Methylcellulose requirement for dry mortar is powder, low water content, and the fineness also requires 20%-60% of particle size to be less than 63um. Fineness affects the solubility of cellulose ether. The coarser Hydroxypropyl Methylcellulose is usually in … Continue reading

The development of dry mortar has changed many times since its inception. In the 1960s and early 1970s, the dry powder mortar factory in Europe adopted a horizontal process, which arranged the raw material warehouse one by one on the ground. The raw materials were first stored in the silos through the lifting equipment, and … Continue reading
Basic Situation of European Dry Mortar In the 1950s and 1960s in Europe, especially in Germany, the demand for the new building materials and technologies in the construction industry grew rapidly, but due to labor shortage at that time(especially the lack of experienced skilled workers), labor costs were very expensive. The construction period has … Continue reading
A cement mortar dry mix essentially comprises of cement, aggregates, resin and a hardener in a single mixture. The hardener is generally present as the reaction product of the hardener with either an organic acid or a functional derivative of it. Dry mix mortar technology is gaining predominant recognition in Europe due to its efficiency … Continue reading
