What are the advantages of ready-mixed mortar? The advantages of ready-mixed mortar are as follows: The first refers to many varieties of mortar. The dry-mixed mortar products in Europe has reached several hundred types, including masonry, plastering, bonding, repairing, decoration and other broad categories, and for each category there are several to dozens of varieties… read more →
What are the advantages of ready-mixed mortar compared with on-site mixed mortar? The raw materials used by on-site mixed mortar are of a single species, with artificial batching employed, and free-fall mixer for stirring. Therefore, the performance of mortar is poor and the quality is unstable. Hollowing, cracking and shedding phenomena are widespread. On-site mixed.. read more →
How is the development of dry-mixed mortar abroad? A: Dry-mixed mortar first originated in Europe. Back in the 1st century, Austria invented the building dry-mixed mortar. Till the 1960s, dry-mixed mortar had got developed rapidly in Europe. The main reason is that Europe needs a lot of construction after World War II, but labor costs.. read more →
What are the economic and social benefits of developing ready-mixed mortar? A: Developing ready-mixed mortar is a major technical and economic measure to save resources and protect the environment, an important content of promoting the transformation of growth mode and adjusting the industrial product structure in the building material field, with significant social, economic and.. read more →
What is the water-retaining and thickening material? The water-retaining and thickening material refers to a type of non-lime materials used in mortar to improve the operability of mortar and to enhance the ability of mortar to retain moisture. The water-retaining and thickening material should have the ability to retain moisture first. Another role is to.. read more →
Why is the water-retaining and thickening material added to all premixed mortar? The water-retaining and thickening material can slow down the water loss rate of mortar. The water loss of mortar includes two processes. One is that the water inside the mortar diffuses to the surface, and the second is that the water on the.. read more →
What are the varieties of water-retaining and thickening material? The water-retaining and thickening material is generally divided into two categories, organic and inorganic, and mainly has a water-retaining and thickening effect. It can adjust the consistency, water retention, cohesiveness and thixotropy of mortar. The commonly used organic water-retaining and thickening material includes methyl cellulose, hydroxypropyl.. read more →
The water-retaining and thickening material can play the following roles: ① To improve the water retention and operability of mortar. Operability includes fluidity, cohesiveness and thixotropic property. If the fluidity is not good, mortar cannot be plastered; if the cohesiveness is not good, mortar is more scattered during plastering, cannot cloud together and cannot maintain.. read more →
The selection of water-retaining and thickening material should be based on the performance, use conditions and construction requirements of dry-mixed mortar. In general, the water retention of mortar is not the higher the better. If the water retention of mortar is too good, it may lead to the prolonged setting time, crusting and decrease in.. read more →
The amount of water used in masonry mortar is 260-300 kg/m3. The main role of controlling the water retention of masonry mortar is to ensure that not too much water of mortar will be absorbed by the block material before setting and hardening; otherwise, the cement in mortar will have no enough water for hydration.. read more →
