Concrete Plasticizer – Capcoplast LA

CapcoPlast LA is a concrete plasticizer, water reducer, and accelerator used to increase the flowability of concrete/mortar without changing the water-to-cement ratio or to decrease the water-to-cement ratio without reducing flowability. This additive also reduces setting time and increases the compressive strength of hardened concrete within one day.

This product is manufactured in accordance with the general requirements of the Iranian National Standard No. 2930-1 and the performance requirements specified in Table 12 of the Iranian National Standard No. 2930-2. Additionally, this additive complies with the requirements of Grade E in ASTM C494 standard and Table 1 of EN 934-1 standard, as well as the requirements of Table 12 in EN 934-2 standard.

Benefits of using concrete plasticizer include:

• Reducing the water-to-cement ratio increases the consistency and compressive strength of the concrete mix within one day.
• Decrease in water absorption and permeability due to the reduced cement-to-water ratio.
• Acceleration in concrete construction time.
• Reduced curing time for concrete in cold weather conditions.
• Faster formwork removal.

The use of concrete plasticizers:

• All types of Concrete Pouring in the Temperature Range Between 5 to 15 Degrees Celsius.
• Producing High-Quality Mortars in Cold Weather Conditions
• Manufacturing Precast Concrete Components under Standard Operating Conditions

Range and Method of Using Additives in Concrete:

Permissible Range for Using Additives in Concrete:

The permissible range of using CapcoPlast LA is from 0.6 to 1.5 percent by weight of cementitious materials (600 to 1500 grams per hundred kilograms of cementitious materials, including cement, silica fume, slag, fly ash, and other similar pozzolans). The determination of the optimal amount of the additive should be based on the specifications of the mix design and the operational and weather conditions, and ultimately, trial mixes should be made. Exceeding the declared permissible limit may have consequences such as an immediate decrease in concrete setting time, especially for concrete containing accelerant cements.

How to Mix Concrete Plasticizer :

To use the additive, it is necessary to dilute it with water in double the volume of the additive. Then, add it to the concrete when it has reached an initial slump of 5 to 8 centimeters. Additionally, the following points should be observed:

After adding the additive, the concrete should be thoroughly mixed for 2 to 5 minutes to ensure complete blending, and uniform distribution of the additive in the concrete.
This additive should not come into direct contact with dry cement or dry aggregate materials.
The volume of water used to dilute the additive (before adding it to the concrete) should be subtracted from the total mixing water in the concrete.
If there is a desire to significantly increase the slump of fresh concrete, the mix design must be formulated in a way that prevents segregation and excessive bleeding of the concrete.
