In concrete construction, material differences, environmental fluctuations, and insufficient material adaptation can easily lead to rapid slump loss, poor aggregate gradation, high powder content (MB value) of machine-made sand, and incompatibility between polycarboxylate admixtures and cementitious materials, which directly affect the performance of concrete and lay quality hazards.
This article briefly explains the diseases, causes, and practical treatment methods of each problem, providing accurate guidance for on-site construction.
