Some situations such as grouting under a wall panel or small base plate for example, will favour installation by dry packing or trowelling in the grout. Some inferior epoxy grouts are cut back with diluents to improve flow but this can lead to excess shrinkage and loss of EBA. Contractors or engineers should refer to the technical data sheet for the specific grout being used for additional suggestions and to help promote successful installations. (2005) presented results of a laboratory investigation of multiple grout injection into clay. As per AISC Design Guide 1, the compressive strength of the grout should be … All other brand names, product names, or trademarks belong to their respective holders. However, experts point out that if the existing cracks in the dam are not completely closed and grouting is done by making holes in the wall, the cement mixture will leak out through the cracks. In order to follow standard grouting procedures, temperatures of the foundation, plates, mixing water and grout should be between 45 -90°F Cold weather retards strength gain and set time. • Position and align the baseplate, leaving a maximum 1–1½ in. Baseplate heights will necessarily vary due to a number of factors, including size of the plates and whether the plate is for a dynamic, vibrating machine or for a static load, structural steel column. In general, process pump manufacturers are asked to provide pumps as a “set” or assembled package comprising pump, driver and base plate (see figure 1). The drill is done until a weak subsoil exists. Products; CS Grout. A baseplate designed to be fully grouted, usually a much lighter construction should be levelled and then fully grouted under the side rails of the baseplate (again, depends on design). Prior to erection of base plate, foundation bolt to sleeve clearance (freeness) is to be checked and foundation bolts with sleeve should be inserted into the pocket provided in the foundation block. Grouting has been extensively used in Singapore for excavation and tunnelling works. It is very important to avoid voids or air pockets in the grout. PROCEDURE GROUTING APPLICATION WORKS. In 2005, ASTM C 1107 was revised to where specific grades of nonshrink grout (Grades A,B and C) are no longer … The depth depends upon how deep the weak subsoil exist. The most vital factor is to fill the void areas in the concrete surface for raising the friction among the steel plate and concrete foundation. If the grouting area is too large for this in a single operation, the following procedure could be a solution: Solution: Divide the area and make several lanes (e.g. If this happens, the grout may crack, threatening the stability of the bond between the two plates. Gaps at the pouring end should not exceed 150mm and at the free end no more than 50mm. Additionally, the grout reduces operational vibrations that can cause structural damage, machinery malfunctions, and machinery damage. Then, the nuts engaging the anchor bolts are secured and the empty spaces within the base plate as well as the space between the baseplate and foundation are filled with epoxy grout. The concrete foundation must be adequately cured before installing and grouting the base. The plate is held down by bolts an- chored in the concrete.
