37 . Mix Proportion and Strength of Concrete Using Super High-Early Strength Portland CementARAKI, KenichiKOHNO, Kiyoshi TAKEMURA, Kazuo
Finally it comes to the conclusion that while making up the ultra-high strength concrete of over 100MPa, it is much more reasonable to appropriately add the mixing amount of the mineral admixtures, increase the water-ce...

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...
The specific mix ratio used in a project will depend on the type and strength of the concrete required, the intended use of the concrete, the exposure conditions, and the availability of materials. It is important to choose the appropriate mix ratio to ensure that the finished concrete meets ...
Mix Ratio of High-strength Concrete Based on Chaotic Particle Swarm Optimization The optimization of the mix ratio of high-strength and high-performance concrete needs to solve the variable design problem of many factors. The purpose of... X Wang - 《Applied Science & Innovative Research》 被引...
In Europe, HPC is considered to be a concrete having a high strength at 28 days (typically >60 MPa in compressive strength) or a low water–binder ratio (<0.40). In USA, HPC is supposed to be a special mixture, matching specific requirements that cannot be achieved on a routine basis....
concrete mix design混凝土配合比设计 1.The fact of that the water cement ratio is the chief factor when making concrete mix design of the airport pavement with this experiment is known.经试验研究得出,水灰比为机场道面混凝土配合比设计中的首要考虑因素,并发现水灰比与混凝土抗折强度具有良好的线性关系...
Compressive strength of concrete is one of the most important elements for an existing building and a new structure to be built. While obtaining the desired compressive strength of concrete with an appropriate mix and curing conditions for a new structure, with non-destructive testing methods for ...
