Self-compacting Liquid Cement for Backfilling Trench
The self-compacting liquid cement for backfilling trench is characterized in that its basic formula is comprised of 100-400 kg of cement, 500-900 kg of local soil, 200-400 kg of stone chips or powder, 50-100 kg of fly ash, accelerating agent or early strength agent accounting for 1-3% of cement weight and a proper amount of water in each cubic meter. Then mixing above materials evenly with a blender and concreting the trench with them. The beneficial effect of the invention is that the invention can avoid the vibration procedure and form by self-weight, which can reduce construction noise, thereby improving the working environment of workers and the living environment of surrounding residents. It can solve the problem of not easy or unable to vibrate and improve the concreting speed, shorten the construction period and reduce the labour intensity of workers. Using local material, it saves material cost as well the cost of earthwork transportation. In addition, it can use industrial waste such as fly-ash, stone chips, etc., which has obvious cost advantages over concrete mortar. Therefore, the invention has significant benefits on economy, society and environment. -1/1 Conventional preparation works and entrance of the construction equipment Installment and debugging of the forced blender. and setting of the necessary dust-proof shed Installation and commissioning of ground pump in situ Site soil selection or screening |Material yard planning and connection of temporary water and electricity Entrance of stone chips or stone Entrance of cement and additives powder and fly-ash Mix and test according to the design proportion Passing the laboratory retest Mixing and producing cement slurry formally Conveying and concreting by pump Figure 1 Flow chart of mixing process of self-compacting liquid cement of the invention
