摘要:
设计了一种免碾压贫混凝土基层，它可有效保证贫混凝土基层的稳定性和平整度，同时可减少施工机械、简化施工工序、缩短周期，改善施工环境。通过研究免碾压贫混凝土基层材料，分析了影响贫混凝土工作性的因素，并提出维勃稠度试验作为其工作性评价方法，以及维勃稠度作为其工作性评价指标。最后，采用多因素正交设计试验，并根据极差分析和方差分析，得到评价指标维勃稠度的回归公式。结果表明，维勃稠度值能够较好地评价免碾压贫混凝土的工作性。
Abstract:
A kind of compaction-free lean concrete (CFLC) base was put forward in this paper. The smoothness and stability of the base could be ensured by using compaction-free lean concrete base. Meanwhile, the construction machinery and construction cycle could be reduced. Also, construction environment could be improved. Factors influence workability of CFLC were analyzed, the method and index of evaluating workability of CFLC were advanced. Orthogonality test design was adopted in tests, regression formula of evaluating index-- Vebe consistency value was educed. The results showed that the workability of CFLC could be evaluated by Vebe consistency value .
