1, DH-4005-type polycarboxylate superplasticizer dosage of 0.4% to 2.5% of the total weight of cementitious material, commonly used dosage of 0.8% to 1.5%. Concrete test should be carried out with a test before use, in order to best dosage. 2, DH-4005-type polycarboxylate superplasticizer not with naphthalene superplasticizer mixed use, must be used when using DH-4005-type polycarboxylate superplasticizer had Naphthalene water reduction blenders and mixers agents might lose otherwise clean water reducing effect. 3. Use the DH-4005 when the Department of polycarboxylate superplasticizer liquid form may be directly mixed with ready-mixed mortar admixture plant in Harbin, can also be formulated into a certain concentration of the solution used and the deduction of Polycarboxylate high performance water-reducing agent into the water itself. 4, due to mixed with DH-4005-type polycarboxylate superplasticizer concrete water reducing rate is high, so the higher the sensitivity to water consumption slump, we must strictly control the use of water. Low Concentration polycarboxylic Concrete, cement raw materials 2.1 Test: PO 42.5R cement, the indicators Ka Wah Cement production line with national standards; ash: Huangpu Power Plant Ⅱ grade fly ash production of high quality ready-mixed mortar Shenyang admixture plant, the indicators in line with regulatory requirements; slag: S95 selection of slag, the indexes meet the requirements; water: water; aggregate: river sand, fineness modulus of 2.5 (1.5% clay content) ready-mixed mortar admixture plant, gravel maximum particle size of 25mm graded gravel (clay content of 0.9%); additive: selection of Guangzhou Sika construction materials Limited production of superplasticizer, model and Jingzhou strong SJX Additive Materials Co., Ltd. of naphthalene superplasticizer, model SF, both of performance to meet the relevant specifications. Ready-mixed mortar admixture plant, high-strength materials, ready-mixed mortar admixture plant Xinji provided by the high-strength Materials Co., Ltd. Linyi City. Ready-mixed mortar admixture plant, high-strength materials, ready-mixed mortar admixture plant Xinji Linyi City high-strength building materials Limited (www.lygqjc.cn) this year introduced a new upgrade, the above picture is for reference only, please call this page or image Contact phone, for the latest information, contact: Zhu Meng income.
