Foam concrete is a vast majority of concrete containing no large aggregates, only fine sand and with extremely lightweight materials containing cement, water and foam. It can be considered relatively homogeneous when compared to normal concrete, as it does not contain coarse aggregate phase. However, the properties of foamed concrete depend on the microstructure and composition, which are influenced by the type of binder used, methods of pre-formation and curing.
High quality foam concrete comes from high quality concrete foaming machine. GF10A cement foam concrete unit is a middle scale foam concrete machine and very hot sale in Asia and Middle East. The mixer and pump system are designed to a whole body so that it become smaller and easy to carry and transport. There is an automatic foaming system inside of this machine, and the volume of additional foam can be adjusted accurately. The pump adopts peristaltic pump which is the best pump for delivering foam concrete, compared with screw pump and piston pump.
Check the slurry and mortar. Check the mix, the proportion of gravimetric test slurry, check the water, cement, sand, and admixture weight ratio meets the design requirements, mortar strength can reach C20.
Check bolt installation and grouting. Puffed holes to install bolt to ensure grouting do not make the slurry bulging. Mortar sealing is 0.5 m deep. After 3 days grouting personnel began grouting, in accordance with the order of the row and row and the order of row encryption.
You should closed mortar standard button. When the suction is less than 0.4L/min continuous irrigation 10 minutes, venting out of the pulp after the closure.
The main advantage of foam concrete is its lightweight, which ensures economy of walls of the lower floors and foundations. It has several advantages and since it is porous in nature, it provides thermal insulation and considerable savings in the material. The important applications of foamed concrete include structural elements, non-structural partitions and thermal insulating materials. Manufacturers developed foam concretes of different densities to suit the above requirements and these products were used in trench reinstatement, bridge abutment, void filling, roof insulation, road sub base, wall construction, tunneling etc.
