）。There are pozzolana, bosolis, #graystone, etc., which are currently widespread in many areas. These things are dried, crushed,
It is used as a concrete admixture as a product by granulation method. These have water absorption properties, change in quality, are unstable, and because they are not calcined, their ion exchange capacity is one-third that of zeolite, so the amount used is also 3.
Conventional admixtures have nearly double the amount. Furthermore, the difference in the ion exchange ability of conventional admixtures that act on concrete is that of potassium (K") and calcium (Ca").

ていないのが特徴である。The difference is in the balance of sodium (Na"), etc., and the fact that surface water (-HzO) and water of crystallization (+H20) are not removed.In particular, conventional admixtures contain potassium (
It is characterized by a small amount of K1) and the fact that water of crystallization (10H20) is not removed.

の特に白華現象を防ぐことができる。The reason gas is adsorbed is because it is porous, and this property can be used to prevent freeze-thaw and efflorescence phenomena, suppress alkaline aggregate reactions, and chemically solve the problems mentioned above due to the properties of zeolite. can be solved. In addition, since it is porous, it can not be used as a substitute for AE agents, but also plays the role of conventional pozzolan, and is a unit of water-cement ratio that is related to the most important strength of concrete, as well as the ease of pouring concrete. It can reduce the amount of water, increase the strength, and prevent the efflorescence phenomenon of conventional concrete.

トを得る事ができる。When mixing zeolite with concrete in a ratio of 5 parts powder to 5 parts granule, the powder has a fast-acting effect, while the granule has a slow-acting effect, and 1 mortar,
It combines with calcium hydroxide, which is a cement irrigation product, in concrete, helps to densify the structure, reduces the unit amount of water, and in particular prevents efflorescence, making it possible to obtain high-quality concrete.

ある為、膨張、収縮の緩和にも役立つのである。It is thought that the released potassium and sodium react with the calcium hydroxide in the concrete to prevent efflorescence, and in fact, the efflorescence of concrete color blocks was prevented. Since zeolite itself is porous, it also helps alleviate expansion and contraction.
