1.Cement Based Grout – High Strength, Non-Shrink, Free Flow
High strength non-shrink, free flow cement-based grout is a construction material commonly used to fill voids, gaps, and spaces in structures such as columns, foundation, and equipment bases. It is a specially formulated mixture of cement, aggregates, and additives that provide high strength, low shrinkage, and flowability.
The cement based grout is commonly used in construction and industrial applications where high compressive and flexural strength, excellent bonding, and durability are required. It is designed to maintain its volume and density, even after setting, and has excellent resistance to chemicals, abrasion, and freeze-thaw cycles.
The high strength non-shrink, free flow cement based grout is typically mixed with water to form a pumpable slurry with a smooth and consistent flow. The mix ratio and consistency of the grout can be adjusted based on the specific application and job requirements. The grout is then pumped or poured into the voids or spaces to fill them completely.
- Core/bore packing
- Foundation grouting.
- Some common applications of high strength non-shrink, free flow cement-based grout include anchoring bolts, dowels, and rebar, filling voids in concrete structures, repairing cracks and joints, and leveling and aligning equipment and machinery.
The application instructions for high strength non-shrink, free flow cement based grout may vary depending on the manufacturer and the specific product being used. However, here are some general guidelines for the application of this type of grout:
- Surface preparation: The surface that the grout will be applied to must be clean, free from dust, debris, and other contaminants that could affect adhesion. The surface should also be roughened or profiled to provide a good bonding surface.
- Mixing: Follow the manufacturer’s instructions to mix the grout with water to the desired consistency. It is important to mix the grout thoroughly to ensure a homogenous mix and avoid lumps.
- Placement: The grout should be placed within the specified working time, which can vary depending on the product. The grout can be poured or pumped into the voids or spaces to be filled, taking care not to trap air pockets.
- Finishing: After the grout is placed, it should be troweled or finished to ensure a smooth and level surface. The surface can also be sealed or covered to prevent evaporation of moisture and ensure proper curing.
- Curing: The grout must be allowed to cure according to the manufacturer’s instructions, which can vary depending on the product. Curing time can be affected by factors such as temperature, humidity, and air circulation.
General Purpose cement based Grout can be placed up to thickness of 100 mm in a single pour when used as an under-plate grout. Placement should be done within 20 minutes post mixing. Make sure the temperature of the mix is Approx. 300C.
Pour the homogeneous mix of the grout into a hopper maintaining the grouting shoulder (150-250 mm)
Stop pouring the grout once it reaches the other end & touches center of the base plate. Cover the exposed areas of grout by wet jute sacks to prevent cracking due to heat generation during curing of grout.
other Area of Use: SmartCare General Purpose Grout can be also used for core/bore packing, filling gaps between concrete members, masonry cavities, anchor bolts etc.
Approximate yield is 11.8 liters at w/p ratio of 0.15 for 25 kg bag
The yield of high strength non-shrink, free flow cement based grout can vary depending on the specific product and application method. The yield refers to the amount of grout produced per unit of volume or weight of the mix.
Generally, the yield of high strength non-shrink, free flow cement based grout is expressed in terms of volume, such as cubic feet (ft³) or cubic meters (m³), or weight, such as pounds (lb) or kilograms (kg). The yield can also vary depending on the water-cement ratio used, the mix design, and the specific application.
To determine the yield of the cement based grout, it is important to refer to the manufacturer’s instructions and specifications for the specific product being used. The manufacturer should provide information on the expected yield and coverage for a given amount of product, as well as the mix ratio and other important details for successful application.
