GQ-213 non-shrink grout Executive Standard: JC / T986-2005 GQ-212 non-shrink grout is pore filling high-strength steel beams prestressed concrete members and the development of new products, is a composite with a highly dispersed chemical additive made A new material polycarboxylic acid liquor, are also widely used in large-scale equipment and the equipment is installed, a large area of ??ground leveling, emergency repair road surface, airport runway fast Buxiu, plugging the tunnel, foundation grouting works. ◎ The main technical performance: ◆ mobility, this grout polycarboxylate liquor in the case of low water-cement ratio, obtained great fluidity polycarboxylate liquor production, 30 minutes liquidity may remain substantially unchanged. ◆ has a micro-expansion effect, filling the site no shrinkage, to ensure a seamless bond at, not loose. ◆ ease of construction polycarboxylate liquor formula, this grout just add water and stir in the field directly. ◆ The compound contained in the mobility component steel corrosion, prevents corrosion of prestressing steel to improve its durability. At present, more and more emphasis on building works performance concrete applications, according to "harbor engineering concrete structure corrosion Technical Specifications" (JTJ 275-2000) for high-performance concrete requirements, based on copolymer carboxylic efficient pumping products performance characteristics, it is completely suitable for use in high performance concrete, but also other types of pumping agent can not be replaced. Polylactic acid synthesis mother liquor liquor _ _ Laibin polycarboxylate high-strength high-strength building materials provided by the Building Materials Co., Linyi. Linyi high-strength building materials Limited (www.lygqjc.cn) to provide "polycarboxylate superplasticizer, polycarboxylate liquor, liquor polycarboxylate" business, the company has "polycarboxylate liquor, polycarboxylate water reducing agents, polycarboxylate pumping agent "and other brands. Focusing on concrete and related products industries, have higher visibility in Linyi. Welcomes inquiries, contact: Zhu Meng income.
