Effects of the material natrue on the concrete workablity

The nature of the material has the following effects on the workability of fresh concrete:

Henan Daswell Machinery Co., Ltd,is a professional manufacturer and trader specializing in the research, development and production of construction machinery for nearly 30 years. Our main products are as follows:SICOMA twin shaft compulsory concrete mixer,concrete batching plants,concrete mixer,blocking making machine,concrete pump,etc.

Aggregate gradation is good, the good work of fine sand; rubble, not good;

The work is good, the needle is more and more, and the work is poor;

Sand ratio is the percentage of the weight of the concrete in the sand and gravel aggregate. The sand ratio is too small, the segregation of concrete bleeding, sand ratio is too large and the amount of cement is low, poor work.

The fineness of cement is finer, less bleeding concrete mixer machine, good work; using too much, the dry shrinkage.

Water cement ratio is the weight ratio of water to cement in concrete. The ratio of large work is good, but the water is concrete mixing plant concrete batch plant, segregation, secrete water, the intensity will be greatly reduced, so the concrete water must strict control. When the water cement ratio is changed, the amount of cement slurry can be increased, and the working performance can be improved.
