发泡混凝土配合比影响及提高强度方式

浏览量:   来源:http://www.shandongsanzhi.com  作者:三智

发泡混凝土的制作主要是以水泥、发泡剂为主料,有时可能加入一些混合材料,还有可能加入细集料加入不同的材料对发泡混凝土的影响也是不一样。


Foamed concrete is mainly made of cement and foaming agent. Sometimes some mixtures may be added, and it is also possible to add fine aggregate to add different materials. The influence of different materials on foamed concrete is also different.


一、仅以水泥和发泡剂的主料,不加其他辅料。这种情况相对比较简单,所用水泥的强度等级越高、用量越多,制备的发泡混凝土强度也就越大。所以当希望制备较高强度的泡沫凝土时,需要选择高强度等级的水泥。


1. The main ingredients of cement and foaming agent are used only, and no other auxiliary materials are added. This situation is relatively simple. The higher the strength grade and the more the amount of cement used, the greater the strength of foamed concrete prepared. So when we want to prepare high strength foam condensate, we need to choose cement with high strength.



二、是加入混合材料:混合材的加入会导致发泡混凝土早期强度的显著降低,而对后期强度的影响并不大。如果添加适当的强度激发剂,则早期强度的降低幅度可以得到减缓。


Secondly, the addition of mixtures: the addition of mixtures will lead to a significant reduction in the early strength of foamed concrete, but has little effect on the later strength. If appropriate strength activator is added, the reduction of early strength can be slowed down.



三、是掺用砂子作细集料,发泡混凝土的强度原则上也会发生不同程度的降低,但是砂子的掺用对提高硬化发泡混凝土的体积稳定性、减小收缩将十分有利。


Thirdly, the strength of foamed concrete will be reduced to some extent by mixing sand as fine aggregate, but the mixing of sand will be very beneficial to improve the volume stability and reduce shrinkage of hardened foamed concrete.



实际施工中往往以同时掺用混合材和砂子的情况为最多见,所以说呢,发泡混凝土的配合比存在一个适宜的范围,需要根据试验确定。然后,今天再给大家分享几个提高发泡混凝土强度的技术的方法:


In actual construction, mixtures of mixtures and sand are often used at the same time, so the mix ratio of foamed concrete has a suitable range, which needs to be determined according to the test. Then, today I will share with you some technical methods to improve the strength of foamed concrete.


1)加强发泡混凝土的早期养护;


1) Strengthening the early maintenance of foamed concrete;



2)选择适宜的配合比;


2) Choosing the appropriate proportion;



3)采用优质高效发泡剂;


3) Using high quality and high efficiency foaming agent;


4)使用高效减水剂并控制适宜的低水灰比。


4) Use superplasticizer and control suitable low water cement ratio.
