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:

一夯架、基面處理不完全：灌漿料使用前，我們要對基面進(jìn)行清理沪峰，清除基面上的油污衙文、不易粘結(jié)的小顆粒、粉塵等嘀拂，同時還要潤濕基面差讼，但不要留明水。倘若基面處理不干凈挤夕，利用設(shè)備基礎(chǔ)二次灌漿料施工時，就會導(dǎo)致粘結(jié)不牢固現(xiàn)象卤竭。

1沪么、 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：在灌漿料施工時锌半，我們要嚴(yán)格按照其水料比進(jìn)行攪拌禽车，同時攪拌時間、攪拌力度要充分刊殉，保障灌漿料攪拌均勻才能使用殉摔。攪拌不均勻的灌漿料會出現(xiàn)充盈度差，容易泌水，強(qiáng)度低逸月，易開裂栓撞。

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.

三碗硬、施工不連續(xù)：灌漿料在進(jìn)行灌漿施工要連續(xù)瓤湘，中途不能間隔太久，同時攪拌好的漿料要一次性使用完畢恩尾，若中途因流動度不夠弛说，不得加水，應(yīng)當(dāng)廢棄翰意。中途加水容易導(dǎo)致泌水舷到，強(qiáng)度不均，開裂現(xiàn)象集蛛。

3夹卒、 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)：灌漿施工時我們應(yīng)從一端向另一端進(jìn)行首捶，或者從中間向四周進(jìn)行鉴何，以排出模板間的空氣，防止氣泡封存與漿料中按冷，切忌為了趕速度從四周同時灌漿矢妄。

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.

五芳乎、養(yǎng)護(hù)不當(dāng)或不養(yǎng)護(hù)：灌漿料施工完畢后汇氛，需進(jìn)行養(yǎng)護(hù)7天左右，通常為灑水養(yǎng)護(hù)捍睡，保障表面處于濕潤狀態(tài)即可呛靡，溫度處于零下時，還要進(jìn)行保溫唧取。如不進(jìn)行養(yǎng)護(hù)會影響灌漿料抗壓強(qiáng)度等性能铅鲤。

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.
