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 mortar belongs to labor-intensive and manual workshop production, low in the productivity and single in the final product. Although the investment is small, the product quality is unstable. Stacking materials on site occupies land. Wastewater, waste, and noise are produced in the production process, not only polluting the environment, but also not conducive to the civilized construction, so it is a phased out production method.
Ready-mixed mortar is mortar of factorization production, with professional and technical personnel in the research and development work of mortar, and the performance of mortar can be adjusted according to the needs of project, so that the quality of mortar can be guaranteed. Usually in mortar more admixtures and additives are added, fundamentally improving the performance of mortar. Mortar is of many varieties and multiple functions.
In addition, the batching of mortar uses the automated and micro-computerized control, so the product quality is stable and reliable. Thus, ready-mixed mortar is not simply moving from the site to the factory production, but high-quality mortar. Promoting ready-mixed mortar is an important technical and economic measure for the technological progress of construction, and an important technical means to guarantee the construction engineering quality, improve the modernization level of construction, and to promote the civilized construction. In addition, the ready-mixed mortar can use the artificially machine-made sand made from construction waste, coal gangues, steel slag and other industrial solid waste to replace the natural sand, which can save natural resources, has no adverse effects on the product quality, and can consume fly ash and other industrial waste. This can not only benefit the waste utilization, but also can reduce environmental damage and achieve the purpose of energy saving and emission reduction.
