Groutings-CapGrout MG

The necessary notes for using the grout and grouting operation:

• Each packet of this product fills 13.5 liters with the minimum amount of water.
• It is necessary to clean the surfaces, joints, and holes from contaminations and dust before grouting. If these surfaces are loose and weak, they should be carved to reach the strong part.
• The surface should be fully submerged at least 2 hours before grouting and discharged from water a little before grouting. Also, it is necessary to fully discharge bolt holes by an air pump.
• The base plates and other steel materials should be clean from oil stains completely.
• For grouting under plates, balancing the base plates is accomplished carefully by using suitable parts (Known as a shim) which are supplied by Capco Company.
• The molding around the grout should be accomplished in a way that there will be no leakage. Using sealing tapes and mastic is recommended for this purpose.
• The suitable amount of water is calculated based on the volume of the desired grout and poured in a mixer with proper volume with an approximate speed of 400 rounds per minute. The amount of water, depending on the required consistency
• varies from 4.5 liters to 5.5 liters per 25 kg grout. Note that this consistency is determined depending on the implementation conditions and the consistency of grout increases in higher range of water; moreover, the strength of grout reduces. Therefore, it is necessary to optimize the suitable amount of water based on the implementation conditions by try and error method. The grout powder is gradually added to the mixture while mixing for up to 5 minutes. The mixing should be done in the minimum time and in a way that obtains a homogenous and uniform mixture.
• Mixing should be accomplished at 20˚C temperature and in a maximum time of 15 minutes to reach the efficiency of grout expansion to its maximum. This mixture is suitable for joints up to 10 cm and the washed dry clean aggregates with a maximum size of 10 mm can be used for bigger joints. In this situation the mixing ratio of sand and grout will be 1:1. This is done to reduce the cement hydration heat in high thicknesses. Besides, the properties of the grout depending on the amount of used sand can be different from the original product.
• Continuous grouting is very important and therefore, the amount of the prepared grout should be proportionate to the volume of grouting. Grouting must be preferably done from one side so that no air is entrapped in the joint. The grout must be pumped for spaces with a high volume of grouting. Also, it is necessary to take the following tips into consideration:
• Grouting must be done continuously
• At temperatures above 25˚C, the considerations about concrete casting in hot weather must be considered.
• Never use an excessive amount of allowable water to obtain higher consistency or to compensate for the decrease in consistency.
