Concrete Plasticizer CapcoPlast PR10

CapcoPlast PR10 is a water-reducing/plasticizing admixture 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 product is manufactured in accordance with the general requirements of the Iranian National Standard No. 2930-1 and the performance requirements specified in Table 10 of the Iranian National Standard No. 2930-2. Additionally, this additive complies with the requirements of Grade D in ASTM C494 standard and Table 1 of EN 934-1 standard, as well as the requirements of Table 10 in EN 934-2 standard.

The physical and chemical specifications of CapcoPlast PR10 are produced within the allowable range of variations specified in the Iranian National Standard No. 1-2930.

The advantages of using a concrete plasticizer include:

• Reducing the water-to-cement ratio in concrete results in uniform consistency and increased compressive strength at 7 and 28 days.
• Reduced water-to-cement ratio leads to decreased water absorption and permeability due to the reduction in water content relative to cementitious materials.
• Improved Cement Distribution, Enhanced Compaction Ability in Various Conditions, and Increased Compressive Strength at Equal Water-to-Cement Ratios.

The use of concrete plasticizers:

• Production and Implementation of Reinforced and Non-Reinforced Concrete
• Production of Cement-Based Mortars
• All types of Concrete Pouring at Normal Room Temperature
• Producing concrete with a water-to-cement ratio between 0.45 to 0.55 and initial slump of 5 to 8 centimeters.
• 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 PR10 is from 0.7 to 2 percent by weight of cementitious materials (700 to 2000 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 increase in concrete setting time, especially for concrete containing retardant 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.
