Nominal mix ratio: This type of mix ratio is based on approximate or “nominal” values, rather than on the actual characteristics of the materials used. Nominal mix ratios are often used for simple construction projects where the concrete does not need to have high strength or durability. Stan...
常用各种混凝土配合比(Commonly used concrete mixture ratio) The post has been viewed 143927 times | back 34 times with conventional C10, C15, C20, C25, C30 concrete Concrete is divided into several grades according to the strength, the strength grade of concrete is based on the cube compressive...
It is well known that concrete structures, like all other structures, are subjected to a loss of strength during their design due to various detrimental factors such as corrosion, weathering and poor maintenance as well as natural calami... V. Raghavendra,T. Suntharavadivel,K Duan 被引量: 3...
Several studies independently have shown that concrete strength development is determined not only by the water-to-cement ratio, but that it also is influenced by the content of other concrete ingredients. High-performance concrete is a highly complex material, which makes modeling its behavior a ve...

Therefore, the water-binder ratio (w_b) is also a characteristic focused on the study. Aggregate, as the component with the largest proportion of the three-phase composition of concrete, also has an important influence on the flexural strength of concrete, so fine aggregate content (Fine_A_...

It is to be noted that the market offers a wide range of concrete admixtures that can reduce the permeability and the water absorption, and obstruct the penetration of harmful liquids and gases without affecting the water-to-cement ratio (W/C) [40]. To reduce the surface absorption and the...
