Artificial machine-made sand is used to make dry mixed mortar, bringing you an unexpected [market [money] scene]
Dry mixed mortar is a standardized product produced with special materials, sophisticated equipment, scientific formula and strict production management. It is one of the emerging dry mixed materials in the field of building materials; At the same time, the dry mixed mortar has the advantages that the on-site mixed mortar does not have; From lime mortar, cement mortar to dry mixed mortar, domestic construction mortar is undergoing a profound transformation. The result of this transformation will make domestic a country with a particularly rapid development and large application of dry mixed mortar. In order to better promote the development of dry mixed mortar, we should clearly understand the current situation, existing problems and future development trend of domestic dry mixed mortar; What are the advantages of producing dry mixed mortar with machine-made sand.
It has the following advantages:
(1) It breaks through the limitation of traditional mortar production process and greatly improves the stability of product quality;
(2) Due to the commercialized production scale, the amortization of fixed costs has been greatly reduced, and cost saving has been achieved on the premise of ensuring quality;
(3) The reduction of intermediate links is conducive to environmental protection;
The production and application of dry mixed mortar is a new technological revolution in the construction industry and building materials industry, and a major direction of the development of building materials in the future.
In the past, the main raw material in the production of dry concrete mortar in domestic was river sand. River sand, after being impacted and polished by running water, has a reasonable grain size distribution and smooth surface. It only needs to add a small amount of cementitious materials and water during the curing process. However, river sand has two major defects. One is that river sand is a limited resource, especially in today's cities, river sand is banned from mining, causing the price of river sand to soar and the cost to rise. The other is, The river sand must be dried before it can be used to make dry mixed mortar, which increases the production cost.
We know that the raw materials of machine-made sand are easy to obtain. Tailings waste, ore mines, etc. can have a large number of raw materials only by obtaining the mining license. Nowadays, the crushing sand making process is increasingly advanced, the sand size can be adjusted, and the output is high. After screening, the sand with a specific size can be obtained and supplied according to the requirements of the demander. In addition, the machine-made sand processing is dry, and it is dried out of order, so the production cost of dry mixed mortar is greatly reduced. The fittest survive by natural selection. It is a general trend for machine-made sand to be used as dry mixed mortar to better meet the market demand.
