1. Study the modification treatment of fluoro-gypsum masonry cement by quicklime, modifier GJ and hemihydrate gypsum, and On this basis, the influence of the activator on the strength of masonry cement is discussed. Finally, the strength, stability and standard are carried out Quasi-consistency water consumption, water retention rate, setting time, swelling and freezing resistance and a series of tests.The test results show that the properties of masonry cement made by this formula meet the national standards and reach 22.5 equal payRequirements.
2. Taking fluoropressum and vitrified microbeads as the main materials, adding alkaline excitation by optimizing the test mix ratioAgent and salt activator, and add fiber, binder and other admixtures, with a small amount of cement to prepare new
The composition, properties and microstructure of the thermal insulation mortar were analyzed. The preparation of Thermal insulation mortar has the advantages of light weight, small thermal conductivity, heat insulation and fire prevention, stable performance and so on. It is a kind of green ring
High performance thermal insulation material.
