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.

Wangan Expressway Way

The bridges and tunnels of the whole line occupy 58.25% of the total length. And there are 5 interchanges,11 separate interchanges, and 2 flyovers in Wangmo-Youmai-Ceheng, Yatta, and Qiaoma. The permanent construction area is 3,167,002㎡ and construction period is 4 years.

Concrete Technical Requirements

Large-volume platform concrete, high-durability concrete, and ultra-high water reducing rate;
The concrete would be good fluidity, good wrapping, moderate viscosity, <20mm slump loss 2.5hrs and no pitted surface;

G25 Changshen Express Road

It is the expanded express road to connect Hangzhou section of the G25 chang-shen, deqing Road with fuyang road section.     Tunnel:4167m
Jinzhuwan tunnel: 2196m
Lion Rock Tunnel: 375m
Holly mountain tunnel: 1145m    1# tunnel:481m
Construction unit:3# China railway

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.
