Truck-mounted concrete pump rear end swing cause

Truck-mounted concrete pump pumping concrete can improve the efficiency of construction projects such as warm, more convenient construction, but concrete pump concrete pumps for cement and other requirements are more stringent. Haomei aggregate truck-mounted concrete pump selection.

Quality pumping concrete water-cement ratio as well as the aggregate size of the slump selection requirements more stringent, so his choice of aggregate and sand rate, what is it, when selecting aggregate certain minimum requirements harmful impurities and the strength of their own to meet the requirements, the choice of the thickness of the aggregate maximum particle size of his main need to meet some of the following conditions, the selected aggregate should not exceed three-quarters of the minimum spacing of the bars can not exceed the minimum structure face longer quarter of its maximum particle diameter of the main duct or need to refer to the inner diameter of the particle size is too large, it will lead to the delivery tube blockage, affecting the smooth pumping.

It is generally to pump concrete aggregate maximum particle size must not exceed one third of the inner diameter of the truck-mounted concrete pump when pumping fine aggregate concrete, mortar effect can not only fill the gaps between the stones, and can play the role of lubrication Therefore, when pumping concrete, it requires a suitable proportion of sand law, not only reduces the friction within the aggregate but also reduces the plastic viscosity, but also improve the performance bond, let the concrete to achieve the best pumping efficiency.
