slump

The slump tests of high-per.

分别对高性能混凝土和自密实混凝土的坍落度试验进行了模拟计算,通过与实测及已有文献的计算结果相比较,验证了该方法的有效性。

The operation management has good interactive Man-Computer interface with improved-functions , especially the factors of certainty and uncertainty which influence the slump have been studied.

该系统人机交互界面友好,功能完善,特别针对影响商品混凝土塌落度的确定和不确定因素研究,采用了前馈控制算法和模糊控制器相结合的方法,使混凝土塌落度逐步逼近到我们所要求的合理范围之内,做到塌落度的自动控制。

Especially with respect to the study on the slump, this paper proposes before-back control algorithm with detecting percent moisture content of sand, in order to meet the mixture ratio results obtained from experiments made by authors.

特别针对商品混凝土塌落度的研究,采用了前馈控制算法,通过测定沙子的含水率来改变实际的物料配比以迎合由大量权威试验得到的配比表。
