15 Concrete Mix Design and Quality Control 混凝土配比设计和质量控制 Concrete mix design can be defined as the procedure by which, for any given set of conditions, the proportions of the constituent materials are chosen so as to produce a concrete with all the required properties for the minimum...
This chapter introduces the commonly used methods of mix design (mixture proportioning) from the United States, and the United Kingdom. The basic principles that are common to all systems are discussed, and then the two methods are considered in detail, stage by stage. Modifications to the ...

The transformation in concrete technology predicted in the 3rd edition of Concrete Mix Design, Quality Control and Specification has arrived, making obsolete many currently published codes and official guidance. In response to these changes, Ken Day, James Aldred, and Barry Hudson present the thoroughl...
However, the lightweight concrete requires specific mix design method that is different from the typical concrete, since using the typical mix method would give rise the material segregation as well as lower the strength by reducing the weight of aggregate. In order to avoid such problems, mix ...
To cope with this problem, an optimisation method for mix design of concrete using Bolomey's law has been used. Following the encouraging results obtained from mortar, a series of tests on concretes with various substitution percentages were carried out to validate the optimisation method. 展开 ...
