Preparation method of autoclaved lightweight high-strength high-fly-ash-content ceramsite
The invention discloses a preparation method of autoclaved lightweight high-strength high-fly-ash-content ceramsite, which comprises the following steps: preparing raw materials, mixing the raw materials, preparing a wet material, performing balling by a balling disc, performing screening, performing natural curing, carrying out moisturizing curing, carrying out autoclaved curing and the like.According to the method, coal ash is mainly used as a main raw material, and the mixing amount of the coal ash reaches 90% or above; The preparation method is a preparation method of the fly ash ceramsitewith a high mixing amount, fly ash is cheap industrial solid waste, and the higher the using amount is, the lower the cost is, so that the cost of unfired fly ash is reduced to a certain extent, meanwhile, the comprehensive utilization way of fly ash is increased, and the comprehensive utilization rate of fly ash is increased. The maintenance process provided by the invention is relatively simpleand effective, cement is hardened through natural maintenance, the ceramsite has certain initial strength, water required by a silicon-calcium reaction is provided for the ceramsite through moisturizing maintenance, the ceramsite is in a humid state, cracking and autoclaved maintenance in the autoclaved maintenance process are avoided, the ceramsite preparation process is simplified, and the utilization rate of raw materials is increased.
本发明公开一种蒸压轻质高强高粉煤灰掺量陶粒制备方法，包括原料准备、原料混合、湿料制备、成球盘成球、筛分、自然养护、保湿养护和蒸压养护等阶段，本发明主要以粉煤灰为主要原料，粉煤灰掺量达到90％以上，是一种高掺量的粉煤灰陶粒制备方法，粉煤灰是一种廉价的工业固废，用量越高，成本越低，这在一定程度上降低了免烧粉煤灰的成本，同时该方法增加了粉煤灰的综合利用途径，提高了其综合利用率。本发明提出的养护工艺，较为简单有效，自然养护使水泥结硬，使陶粒具有一定的初期强度，保湿养护为陶粒提供硅钙反应所需用水，并且使陶粒处于潮湿状态，避免在蒸压养护过程中开裂，蒸压养护，简化了陶粒制备工艺，提高了原料的利用率。
