As a new semiconductor material, cubic boron arsenide has good application prospects
Cubic boron arsenide is a new type of semiconductor material that has the advantages of high electron and hole mobility and high thermal conductivity. It is expected to be widely used in solar cells, …
Cubic boron nitride (CBN) has broad application prospects and domestic production capacity is mainly concentrated in central China.
Cubic boron nitride, or CBN for short, is a new type of artificially synthesized superhard material. Its atomic structure is similar to the carbon atomic structure in diamond. It has a hardness second…
How to calculate how much water reducing agent is used for one cubic meter of concrete?
What is the main component of the water-reducing agent? Lignin sulfur calcium (agent) is generally 0.2%~0.5%. Naphthalene-based water-reducing agent is generally 0.5%~0.75 % Water-soluble water-solubl…
If 100 cubic meters of concrete plus retarder requires a retarding time of 6 hours, how much retarder should be used?
The dosage of retarder should be determined based on experiments. For example: Calculated based on four ten thousandths of the cementitious material, assuming 400*0.0004=0.16kg/m3 Then 100 cubic meter…
