C15, C20, C25 and C30 are commonly used for rural self built houses, and the cement is 325# cement. Brick concrete structure: C15 strength is used for foundation cushion, and C20 or C25 strength concrete is used for strip foundation, column, slab and beam. Frame structure: C15 strength is used for foundation cushion, and C30 strength concrete is used for independent foundation, column, slab and be...
1.mixer and batching system During the operation of the transmission system and equipment, the lubricating oil of each transmission gear, reduction gearbox and chain shall be fully added according to the regulations. At the same time, the equipment shall be inspected in detail to avoid problems in the operation process and affect the work efficiency. In case of bearing oil leakage, heating and bra...
1. Influence of cement mineral composition As we all know, there are four main constituent minerals of Portland cement. Their hydration properties are different and their proportion in cement affects the overall properties of cement. Although C3a contributes greatly to the early strength, the hydration heat is several times of other minerals. Therefore, early strength cement with high C3a content ...
Project background The large-scale pouring of large hydro power dams, nuclear power plants, high-speed railways and high-rise building foundations requires the use of temperature-controlled concrete. In the process of concrete mixing, the internal volume of concrete hydration heat increases, especially in the high temperature working conditions for mixing generated heat is higher, in the later cur...
Stationary continuous mixing plants equip with a continuous mixer and a continuous batching system for aggregates, powder materials, water and others, it discharges materials continuously in production, with the output capacity range from 300 to 800 ton/hour. So it widely used to produce a variety of substrate materials for roads, dams, airport runways and so on. It’s also widely known as stabiliz...
Before starting up the sabilized soil mixing plant: please do all checks as bellow: 1. Check whether all bolts are fastened, especially the mixing blade in the twin shaft continuous mixer and the vibrator blade of each hopper. 2.Check whether there is any missing place for the belt roller and whether the rotation position is fully lubricated. Each bearing of the mixer is lubricated once every...
Summer has the climate characteristics of high temperature, much precipitation, large precipitation and fast drying, which are embodied in high external temperature, low air humidity, strong sunlight and fast water evaporation. Although the higher temperature in summer is beneficial to the early growth of concrete strength, there are also disadvantages such as high temperature, slump loss, rapid w...
Concrete batching plant produced by Fujian Xinda Machinery Co., LTD., The aggregate batcher can be designed to be underground, partially underground or on the ground. The aggregate hopper could be 3-5 hoppers according to concrete mixing design. Through computer-controlled air cylinders and the open speed of discharge door,the aggregate is discharged into the weighing hopper. When the target value...
Concrete mixing station presents four major development directions 1. Environmentally friendly The low environmental protection of my country's concrete mixing station will improve and improve from three aspects of dust, noise and pollution. In terms of dust, it should be controlled in the transport path of powder, such as adopt imported dust collector on cement silos, mixing tower adding a dust c...
