Example Embodiment
[0031] Embodiment one
[0032] 1. Take 400Kg of sandy soil from which debris such as large stones and bricks have been removed;
[0033] 2. Take 300Kg of pozzolan cement and 270Kg of mixed water, pour the three components into the mixer and mix them evenly; the pozzolan cement mainly plays the role of consolidation and strengthening the skeleton of the soil, and the same amount of ordinary silicate can also be used for pozzolan cement Cement or blast furnace Portland cement, etc., after these materials are added to the soil, water will react with water to produce Ca(OH) 2 Product, Ca(OH) 2 Ion exchange with clay particles to form a solidified product, to achieve the role of strengthening the skeleton of the soil. In addition, a curing auxiliary agent for the purpose of catalysis and early setting is added to the above cement. The curing auxiliary agent is fly ash, gypsum powder or silicon powder, etc. The purpose of adding these materials is also to reduce the amount of ceme...
Example Embodiment
[0035] Embodiment two
[0036] Directly take 550Kg of ordinary Portland cement and 400Kg of mixed water and pour them into the blender to stir and mix evenly; add 50Kg of air bubbles to the mixture and let the air bubbles evenly distribute in the mixture by stirring to obtain air bubbles that can be used for pouring immediately Mix in light soil. In a dry state, the pore volume formed by air bubbles in the light soil mixed with air bubbles in this embodiment accounts for about 65% of the total volume.
Example Embodiment
[0037] Embodiment three
[0038] Take 660Kg of sandy soil, 120Kg of blast furnace Portland cement, and 210Kg of mixed water, pour the three components into the mixer and mix them evenly; then add 10Kg of air bubbles to the mixture and let the air bubbles evenly distribute in the mixture by stirring In the process, air-mixed light soil that can be used for pouring immediately is obtained. In a dry state, the volume of pores formed by air bubbles in the light soil mixed with air bubbles in this embodiment accounts for about 40% of the total volume.
