The so-called effective content of white ash refers to the content of calcium oxide (CaO) and magnesium oxide (MgO) contained in white ash, which play a decisive role in the strength of the lime-ash crushed stone base, especially After the hydration reaction with fly ash, the effect of the content of the fly ash is more significant. A certain increase in the lime dose can naturally increase the strength of the ash gravel, but this not only increases the construction cost, but also increases the The crack resistance of the ash gravel base layer is also very disadvantageous. Therefore, white ash with high effective content should be selected as much as possible. Generally, white ash must meet the standard of secondary ash, that is, the content of effective calcium and magnesium oxide in white ash is not less than 80%, which can satisfy the oxidation and water of the ash and gravel base. The need for chemical molding ensures the strength of the base layer and improves the stability of the base layer without affecting its crack resistance. It is very beneficial to ensure the quality of the base layer. The digestion of quicklime is an important part of construction mixing. The specific process should be effectively controlled. The digestion of quicklime is actually a CaO (MgO) hydration (H2O) exothermic reaction process, which must be properly controlled. Adding water and adding water speed, so that the slaked lime after digestion can not be too dry and "damp", nor can it be too wet and "bonded soft", the surface looks loose, the measured water content does not exceed 35%, in order to benefit two The uniform mixing of the gray stone mixture is usually carried out in advance in the construction process to meet the construction needs (previous digestion time is generally 7-10 days).
