At normal temperature season, how many days should the lime soil grass needs irrigation?
In theory, the best water content of lime soil is the optimum water content of plain soil, the amount of water needed for evaporation in the process of mixing and the amount of water needed for the reaction of lime, and the sum of the three. Lime soils with different soil and lime dosages have different optimum water contents, which need to be obtained through experiments. When the lime soil is compacted in the best water content, the maximum density can be obtained. The water content should be tested separately during the process of mixing and rolling. When rolling, the moisture content of the mixture can be slightly larger than the optimum moisture content by 0.5% to 1%, which is to compensate for the loss of water during the rolling process. Too much water content will affect the density and strength that lime soil may reach, and will increase the dry shrinkage of lime soil obviously, and cause dry shrinkage cracks in the structure layer. Too little water content also affects the density and strength that lime soil may reach.
Moisture is an important component of lime soil. In construction, the soil moisture in the lime and soil physical and chemical effects, in order to meet the needs of the strength of lime soil; lime soil moisture has certain plasticity in compaction, in order to facilitate rolling to the required degree of compaction; the lime soil moisture health has certain humidity, meet the strength required for the formation in the process of water. Therefore, the best moisture content is also a key indicator to control the quality of lime soil construction.
