This product recommended dosage is 0.25% -0.85% of the total weight of cementitious
material, actually content should be experimentally determined.
1. HL-800 is always diluted to 10% to 20% concentration for use.
For example, to make 1 ton of HL-800 solution(10%), please fully dilute 200kg of HL-800 (50%) into 800kg of
2. When the weather is hot, making concrete with HL-800, a certain amount of retarding agent and air-entraining
agent need to be added in the HL-800 solution (10%). On special occasions when slump loss of concrete speeds
up and segregation appears after casting, it’s necessary to add plastic retaining agent (or add our product of
SR-1). Here’s the general formula to compound HL-800.
HL-800 solution (10%): 980kg
Retarding Agent: 15-20kg
Air-entraining Agent: 2kg
The dosage of the finished product is 2.0-3.0% by weight of cement.
