The workability of new mortar refers to whether the mortar can form a uniform and continuous thin layer when laying surfaces such as bricks and stones, and tightly bond with the base layer. This involves two aspects: fluidity and water retention.
Firstly, fluidity is an important factor affecting the fluidity of mortar, including the type and dosage of cementitious materials, water consumption, as well as the type, particle shape, fineness, and grading of fine aggregates. In general, when the substrate is a porous and absorbent material, or when construction is carried out under dry and hot conditions, mortar with high fluidity should be selected. On the contrary, if the base has low water absorption or is constructed under wet and cold conditions, mortar with less fluidity should be selected.
Secondly, water retention refers to the ability of mortar to retain moisture. Mortars with poor water retention are prone to bleeding and bleeding during use, resulting in weak bonding between the mortar and the substrate. At the same time, water loss can affect the normal hardening and strength of the mortar. The factors that affect the water retention of mortar mainly include the type and dosage of cementitious materials, the type, fineness, and water consumption of sand, etc. Adding powdered mixtures such as lime paste and fly ash to mortar can improve its water retention.
In addition, factors that affect the strength of mortar include the type and dosage of cement, the type of sand, the use of admixtures, the mixed materials added, and the masonry and maintenance conditions. When the quality of raw materials is constant, the strength of mortar mainly depends on the grade and dosage of cement. In addition, the content of mud and other impurities in the sand can also affect the strength of the mortar.
Thermal insulation mortar is a type of mortar made by mixing cementitious materials and lightweight porous aggregates in proportion, also known as thermal insulation mortar. It has properties such as lightweight, |
