What is shrinkage compensated grout?
Shrinkage Compensated Construction Grout. Compensates for shrinkage and allows controlled expansion with maximum strength.
What is dual shrinkage grout?
DUAL SHRINKAGE COMPENSATED HIGH STRENGTH CEMENTITIOUS GROUT FOR APPLICATIONS FROM 10MM TO 100MM. SikaGrout-212 HP is a cementitious, non-shrink, high performance grout that expands in two stages in both the plastic and hardened states (class A and C) to counteract the shrinkage normally associated with cement grouts.
What is shrinkage compensated?
Shrinkage-compensating concrete is made with an expansive cement or expansive component system in which initial expansion, if properly restrained, offsets strains caused by drying shrinkage. Shrinkage-compensating concrete is used to minimize cracking and structural movement caused by drying shrinkage in concrete.
Does non shrink grout crack?
Cement based repair mortars, non-shrink grouts or concretes may form fine plastic shrinkage cracks when exposed to hot weather conditions.
What is a Class A grout?
Class A Superstrength Grout is a higher strength premixed cement based, non-ferrous, non-shrink grout, exhibiting good flow characteristics. This extra performance grout offers the advantage of low water requirements and high compressive strengths.
What is Type K cement?
Type K cement is an expansive cement, as defined by ASTM C845. [1] Type K cement contains anhydrous calcium aluminate, which contributes to its expansive properties. [2] Compared to conventional Type I cement, Type K cement exhibits a greater increase in volume during hydration.
What is Class C grout?
Class C grouts: (also known as Performance Grouts) are shrinkage compensated (non-shrink) during both the plastic and post hardened state.
What is mass concrete construction?
It defines mass concrete as: Mass concrete is usually associated with large, poured in-situ concrete structures such as dams, bridge piers, foundations to very tall buildings and other large volume placements which are at least 1m-deep.
How thick can non shrink grout be?
For many applications, it may be placed up to 6 inches (150 mm) in depth without the extension. When placing at depths over 3 inches (75 mm) and the surface area is over 2 ft2 (0.19 m2), the product should be extended.
What is Sika grout?
SikaGrout®-215 is a pumpable dual-shrinkage compensated, self-levelling, prebagged cementitious grout with extended working time to suit local ambient temperatures. USES. SikaGrout®-215 is suitable for repairs to the following concrete structures: Machine foundations. Columns in precast construction.
What is dual shrinkage Sika Grout?
DUAL SHRINKAGE COMPENSATED HIGH STRENGTH CEMENTITIOUS GROUT FOR APPLICATIONS FROM 10MM TO 100MM. SikaGrout-212 HP is a cementitious, non-shrink, high performance grout that expands in two stages in both the plastic and hardened states (class A and C) to counteract the shrinkage normally associated with cement grouts.
What is the shrinkage of grout?
shrinkage, we can limit it to a point where it becomes insignificant to the final result on site. Two types of shrinkage exist in cement based grouts – shrinkage in the “plastic” phase and “long term drying shrinkage” in the hardened phase of the grout. Severalon site
What is shrinkage compensating concrete?
A: Shrinkage-compensating concrete is made with either expansive cement, or with normal cement and an expansive component that’s added separately. It’s proportioned so the concrete will increase in volume after setting and during early-age hardening.
What is epoxy based grout?
Epoxy resin based grouts are generally formulated to be used within a range of gap sizes to ensure shrinkage is controlled. One of the features of epoxy based grouts is their ability to bond to the concrete foundation and the base plate.
