Embodiment 1
[0034] An autoclaved fly ash brick (strength grade 10MPa) is composed of the following raw materials in the following weight ratio: 80% fly ash, 10% sand, and 10% quicklime.
[0035] Such as figure 1 Shown, the production technology of this autoclaved fly ash brick comprises the steps:
[0036] S1: Raw material storage and preparation:
[0037] (1) Fly ash: Fly ash is divided into wet fly ash and dry fly ash. The wet fly ash is directly sent to the factory shed for storage, and the dry fly ash is transported into the factory and then pneumatically transported to the fly ash. stockpiled for use;
[0038] (2) Sand: The sand is transported to the shed in the factory and poured into the storage hopper of the aggregate batching machine by a forklift for storage for later use;
[0039] (3) Quicklime: block quicklime is first crushed into lime particles with a particle size of ≤25mm by a jaw crusher, then sent to the quicklime storehouse for storage by a bucket elevator, and then ...
