What are the water stabilized materials often mentioned in engineering? First, we need to know what is the water stable layer? Water-stabilized layer is the abbreviation of cement stabilized gravel layer, that is, cement consolidated graded gravel is used, and it is completed through compaction and maintenance. Water-stabilized materials are mainly composed of aggregate and mortar volume. It covers the following categories:
As a stabilizer of aggregate, the quality of cement is crucial to the quality of aggregate. Cement with long final setting time and low grade shall be selected during construction.
2. Mixed materials
Mixed materials are divided into active and inactive materials. Active materials refer to materials such as fly ash, which can react with calcium oxide precipitated from cement. Non-active materials refer to artificial or natural mineral materials with no activity or very low activity. The quality requirements for such materials are the fineness of materials and the absence of harmful ingredients.
Artificial aggregate shall be used. When used as subbase in road works, the large particle size of aggregate shall not exceed 40mm. The particle composition range shall be based on the No. 1 grading in Table 2. When used as base, the large particle size of aggregate shall not exceed 30mm.
Generally suitable for drinking, water can be mixed and maintained. If there is any doubt about the water quality, it is necessary to conduct tests to determine whether there are substances in the water that have a significant impact on the development of cement strength. If the ratio of compressive strength of cement mortar made from water taken from the water source to that of cement mortar made from distilled water is lower than 90%, such water shall not be used for water stabilization construction.
