To study the problem of collapse mode cracking in the cast-in-place foam concrete wall, using ordinary Portland cement, fly ash, and self-made composite foaming agent as the primary raw materials, the admixtures (there are two kinds of admixtures) we
Lithium batteries were first used in pacemakers.
Other five kinds of water-reducing agents: sulfamate high-efficient water reducer, fatty acids high-efficient water reducer, HSB aliphatic superplasticizer, powder polycarboxylate, casein will be introduced.
Natural flake graphite are widely used in advanced refractories and coatings in the metallurgical industry. Such as magnesia carbon bricks, crucibles, etc.
Foam concrete wall casting methods can be divided into three types: removable formwork casting, formwork-free casting and sandwich wall casting. Among these three types of casting methods, the mold-free casting method is widely used.
Recently, Tang Yongbing, a researcher at the Functional Thin Film Materials Research Center of the Shenzhen Institute of Advanced Technology, Chinese Academy of Sciences (hereinafter referred to as Shenzhen Advanced Institute), and the team of Zheng
