This paper presents an investigation into the effect of a modified zeolite additive (PWC) on strength and durability behaviour of concrete. The additive, a blend of selected alkaloids and zeolite, is commercially available and effectively used in soil stabilization for road construction.

ingredients of mortar or concrete during mixing. These enable the concrete to meet requirement of job specification such as to provide modification there by improving the quality of plastic concrete, reduce the cost of concreting operation and improve the quality of hardened concrete. Admixture may also be

Concrete Admixtures. Admixtures are materials in form of powder or fluids that are added to concrete to give it certain characteristics not obtainable with plain concrete mixing

Concrete surfaces should be clean, sound and free from oil, grease, laitance and loosely adhering particles. Metal surfaces (iron and steel) should be free from scale, rust, oil and grease. All absorbent surfaces must be well saturated with clean water, but be free of any surface water or puddles prior to the

Additives are the materials which are added to the concrete as the replacement of certain amount of cement. Besides improving certain properties in fresh state they also improves the hardened properties of concrete. XCalibur produces a variety of additives which can be used as cement replacement and can improve many properties of concrete.

Nov 20, 2018· It can be seen that the WRA can prolong final setting time slightly, which can be controlled in the range of 30 to 38 min. The reason is that the polar hydrophobic groups of WRA are attracted on the surface of cement particles, and form a stable protective .

concrete additive for high water retention of the mixture to achieve high density of face and core concrete; for paving stones, slabs and kerbstones proven in largeformat paving slabs

By using this type of material added will be achieved three things, namely: Just add / improve your work skills. By adding WRA into the concrete then with the same fas (moisture content and cement) we will get concrete with a higher degeneration value. With higher slope, fresh concrete will be more easily poured, stirred and compacted.

The concrete composition must be established in order to assure the resistance and durability of building elements, by using less cement dosage. The concrete composition is established by the next parameters: concrete class which is indicated by the designer; cement type; additive type according to the requirements from the project;
