Cebex CP is supplied as a powder additive. The material is a combination of additives that allows the use of a low water/cement ratio with a consequent increase in strength and durability.

An expansion that prevents natural settling and plastic shrinkage of the grout helping its stability and cohesion, while completely eliminating segregation and exudation of the grout.

Similar characteristics to Cebex NK ( See descriptive sheet ).

Properties

The following results were obtained at a temperature of 20ºC:

• Appearance: White powder
• Density: 0,57 gr/cm3
• Chloride ion content: ≤ 0,10% by mass
• Setting times: Cebex CP does not noticeably affect the setting times of cementitious grouts.
• Main application: Cementitious slurries without segregation.

Dosage

The recommended dosage depends on the type of cement and the desired w/c ratio. As a guideline, the dosage is between 1.0% and 2.0% s.p.c.

Effects of overdosage

Overdosage of Cebex CP increases the flowability of the slurry and may cause air entrapment.

Application

Surfaces to be grouted should be prepared ensuring clean, sound and previously water saturated substrates. Free expanding surfaces should be minimised. Grout within 20 minutes of mixing to maximise the expansion process. The usual methods of placing or pumping should be adopted so that the application is continuous.

The grout obtained with Cebex CP can be pumped up to 2 hours after grouting, depending on the type of cement and temperature.
