In actual construction, problems such as incomplete curing and surface cracking may be encountered. This article proposes professional solutions to these common problems.
1. Surface peeling and cracking
reason: Improper maintenance, excessive moisture evaporation, or excessive compaction leading to shear failure.
Countermeasures: Strengthen watering maintenance and cover with geotextile; strictly control the number of compaction passes and moisture content.
2. Insufficient strength
reason: Insufficient dosage of curing agent; uneven mixing; excessive soil organic matter content.
Countermeasures: Recheck the mix ratio; increase the number of mixing passes; high organic matter soil needs to be improved first.
reason:
reason: The moisture content is too high, resulting in elastic deformation of the soil during rolling.
Countermeasures: Carry out drying, reduce the moisture content to the optimal moisture content range of ±2%, and then roll.
