Is it difficult to distinguish between dry mixed mortar and wet mixed mortar? Teach you how to easily choose mortar – Part Two
Sand is treated in different ways:
The sand for wet mixed mortar does not need to be dried, while the sand for dry mixed mortar needs to be dried.
Transport equipment is different:
Wet mixed mortar, the transportation radius is within 40 kilometers, and the transportation time is not more than one hour. Each ton of wet mortar contains 170-190 kilograms of water, which is 15% more than the transport volume of dry mixed mortar, and the electricity consumption required for the production of this part and the fuel consumption of transportation will increase a certain cost. Wet mixed mortar is usually transported centrally by mixing tank trucks to ensure that the mortar does not produce stratification and segregation during transportation. At present, the usual tank car volume of concrete enterprises is 9 square, and it is necessary to have a large construction surface and construction personnel at the same time to consume the wet mixed mortar transported every day, and the supply method of “small number of times” is the reason for the high transportation cost of wet mixed mortar.
Transport mode of wet mixed mortar: dry mixed mortar, transport radius can radiate to 80 kilometers, bulk dry mixed mortar can be transported by tank truck, bag can be transported by car, manufacturers can reasonably arrange the time, make full use of vehicles. 1000 square of dry mixed mortar, there are 35 cars is enough, its time requirements are not very strict, the manufacturer is very reasonable to arrange the use of vehicles. Can be stored for a long time, construction rain or shine, with use. However, it will increase the purchase cost of mobile silos, logistics vehicles and bulk packaging equipment, and the investment is large.
Bulk dry mix mortar is transported by back tank truck:
Cost analysis:
From the perspective of cost, because wet mixed mortar can be chosen to share with the concrete mixing station, the output of wet mixed mortar and concrete can be superimposed together to achieve the purpose of dual-use in one station, so its equipment investment and production cost are greatly reduced compared with dry mixed mortar.
Taking Guangzhou as an example, within the region, according to the comprehensive cost consideration, the dry mixed mortar of the same type is compared with wet mixed mortar. If it is converted into tons, according to the price of mortar to the site, wet mixed mortar is more than 40 yuan cheaper than dry mixed mortar per ton. If the construction cost of mortar is extended to the later stage, the construction cost of wet mixed mortar is about 1 yuan cheaper per square meter than that of dry mixed mortar.
