Many large equipment need to be fixed on the high-strength base surface to operate, and the strength and fatigue resistance of concrete structures can not meet the equipment operation requirements, so we need to use grouting materials to reinforce them. If some small details are omitted during the secondary grouting of equipment foundation, the grouting effect will be greatly reduced. What problems are likely to occur when grouting materials are not used properly? Jinan putty powder manufacturer analyzes for you:

一、基面處理不完全：灌漿料使用前，我們要對(duì)基面進(jìn)行清理，清除基面上的油污、不易粘結(jié)的小顆粒、粉塵等，同時(shí)還要潤(rùn)濕基面，但不要留明水。倘若基面處理不干凈，利用設(shè)備基礎(chǔ)二次灌漿料施工時(shí)，就會(huì)導(dǎo)致粘結(jié)不牢固現(xiàn)象。

1、 Incomplete treatment of the base surface: before using the grouting material, we should clean the base surface, remove the oil dirt, small particles that are not easy to bind, dust, etc. on the base surface, and also wet the base surface, but do not leave open water. If the base surface is not cleaned, the bonding will not be firm when the secondary grouting material for equipment foundation is used for construction.

二、攪拌不均勻：在灌漿料施工時(shí)，我們要嚴(yán)格按照其水料比進(jìn)行攪拌，同時(shí)攪拌時(shí)間、攪拌力度要充分，保障灌漿料攪拌均勻才能使用。攪拌不均勻的灌漿料會(huì)出現(xiàn)充盈度差，容易泌水，強(qiáng)度低，易開裂。

2、 Uneven mixing: during the construction of grouting materials, we should mix them in strict accordance with their water-material ratio, and at the same time, the mixing time and mixing strength should be sufficient to ensure that the grouting materials can be mixed evenly before use. Uneven mixing of grout will lead to poor filling, easy bleeding, low strength and easy cracking.

三、施工不連續(xù)：灌漿料在進(jìn)行灌漿施工要連續(xù)，中途不能間隔太久，同時(shí)攪拌好的漿料要一次性使用完畢，若中途因流動(dòng)度不夠，不得加水，應(yīng)當(dāng)廢棄。中途加水容易導(dǎo)致泌水，強(qiáng)度不均，開裂現(xiàn)象。

3、 Discontinuous construction: The grouting material shall be continuous during the grouting construction, and the interval shall not be too long. Meanwhile, the mixed grout shall be used at one time. If the fluidity is insufficient during the grouting construction, no water shall be added, and it shall be discarded. Adding water halfway can easily lead to bleeding, uneven strength and cracking.

四、施工方位不當(dāng)：灌漿施工時(shí)我們應(yīng)從一端向另一端進(jìn)行，或者從中間向四周進(jìn)行，以排出模板間的空氣，防止氣泡封存與漿料中，切忌為了趕速度從四周同時(shí)灌漿。

4、 Improper construction orientation: during grouting construction, we should carry out from one end to the other end, or from the middle to the four sides, so as to exhaust the air between the formwork and prevent bubbles from being sealed in the slurry, and we should not grout from the four sides at the same time in order to catch up.

五、養(yǎng)護(hù)不當(dāng)或不養(yǎng)護(hù)：灌漿料施工完畢后，需進(jìn)行養(yǎng)護(hù)7天左右，通常為灑水養(yǎng)護(hù)，保障表面處于濕潤(rùn)狀態(tài)即可，溫度處于零下時(shí)，還要進(jìn)行保溫。如不進(jìn)行養(yǎng)護(hù)會(huì)影響灌漿料抗壓強(qiáng)度等性能。

5、 Improper or no curing: After the completion of the grouting material construction, it needs to be cured for about 7 days, usually by sprinkling water to ensure that the surface is in a wet state. When the temperature is below zero, it also needs to be insulated. Without curing, the compressive strength and other properties of the grouting material will be affected.
