Application of the Ready-mix Concrete for Roads and Expressways’ Projects
High Range Polycarboxylate Superplasticizers
Made from KZJpoint 804T, KZJpoint 810T and KZJpoint 811A
KZJ products are suitable for all types of ready-mixed and precast concrete, from very basic to ultra-high strength, use in the construction of high-rise buildings, bridges, tunnels, high-speed railways, roads, airports, ports, dams, hydraulic & municipal engineerings. Our various concrete admixtures are able to improve strength,setting time, slump retention, appearance and enhance its durability as well. These properties make the concrete placing, pumping and finishing more easily.

Middle Route Project of South-North Water Diversion
(China's major strategic project)
The Technical Difficulties of C35 underwater cast-in-place concrete in this project are:
The traffic condition requires the concrete to have slump retention of more than 500mm after 2hrs to meet underwater pumping. Moreover, The depth of the underwater pile in 35m, and continuous pouring is required, which requires good concrete flowability and workability
KZJ Solution:
We introduced the slump-preserving agent and regulator in the admixture formula, adjusted te dosage of retarding ingredients reasonably, solved the problem of stone powder collapse completely, and finally meet the requirements of construction pumping, impermeability and sulfate resistance durability.
