On September 23, the review meeting of the rigid Waterproof Engineering Protection Engineering (Draft Regulations) (hereinafter referred to as the Regulations) was held in Beijing. The review expert group unanimously agreed that the Regulations would pass the review.

Review organized by China engineering construction standardization association waterproof protection and repair committee, competent departments of China engineering construction standardization association Zhang Hongyan, secretary general Huang Jing, deputy secretary general Wang Hailong, chief unit China research institute research building materials co., LTD., chairman of the board, China research institute construction research technology co., LTD., Chen Qian, Wang Yonghai, deputy director of China construction materials science research co., LTD., professor Zhao Shunzeng, chairman Dr Yao Guoyou more than 60 people attended the meeting.

Conference established in suzhou non-metal mining industry design and institute co., LTD. Professor Shen Chunlin senior engineering as group leader, military academy of national defense engineering institute of protection engineering institute as deputy leader, Beijing construction engineering institute co., LTD., professor Ye Jinbiao, southeast university, housing and urban-rural construction qualification registration center Guo Baoming senior architect, China concrete and cement products association waterproof and repair technology branch professor Liu Li, ministry of transportation highway science research institute researcher Wang Jiliang review expert group.

Expert group listened to the professor yong-hai wang high engineering work report, a comprehensive review of the regulations content, think the regulations content scientific and reasonable, operability, coordination with the current relevant standards, innovation put forward the waterproof concrete resistance and its evaluation method, concrete structure from waterproof design requirements, improve the rigid waterproof standard system, reach the international advanced level, agreed to the regulations passed the review.

The Regulations systematically stipulate the material requirements, design, construction and quality acceptance of the rigid waterproof system, which has a guiding significance to guide and standardize the development of the rigid waterproof technology, and provides a standard basis for the rigid waterproof system or the waterproof system with the rigid waterproof as the main body.

Jiagushi is the director unit of the Waterproof Protection and Restoration Professional Committee of China Engineering Construction Standardization Association and the participant of the Regulations. Dr. Yao Guoyou, chairman of the board, is the expert member of the committee, who actively participates in the compilation of the Regulations, and puts forward positive opinions and suggestions for promoting the development of rigid waterproof technology.

Rigid waterproof is to rely on the tightness of the structure component itself or the use of rigid material as a waterproof layer to achieve the waterproof purpose of the building.The core products of Jiagushi's, SJ-1 self-healing inorganic proliferator and SK series nanosilicon ion permeable modifier, are both rigid waterproof materials.

SJ-1 self-healing inorganic proliferator is concrete mixed waterproof material, containing amorphous active silicon and water, cement calcium hydroxide reaction, generate calcium silicate crystals, large Angle, large area of filling concrete capillary holes, micro cracks, improve density, make the healing of the cracks, and permanent waterproof moisture resistance, also can greatly extend the life of concrete.

SK series nanosilicon ion permeable modifier is concrete external injection material, can deeply penetrate into the concrete interior 30-50mm for chemical reaction, generate calcium silicate crystal fully filled into the concrete internal pores and subtle cracks, make the concrete tightness is better, which can inhibit the production of concrete crack, improve the waterproof level, cut off the seepage channel, fundamentally solve the problem of building water leakage.

The proliferative agent and nano-silicon ion permeable modifier jointly form a good solid permeable crystalline self-healing waterproof system, combined with internal and external injection, complement each other, not only activate the self-healing performance of the concrete, but also gives the waterproof protection with the same life of the concrete structure, to solve the problem of permanent waterproof, and greatly extend the service life of the structure.
