Embodiment 1
[0054] Embodiment 1: the preparation method of aerated concrete block
[0055] Concrete preparation method comprises the following steps:
[0056] (1) Raw material processing
[0057] ①Fly ash fineness: 33.5%, fly ash loss on ignition: 5.3%,
[0058] Fly ash fineness refers to the proportion of fly ash left on the sieve to the total fly ash after passing through a 0.045mm square hole sieve;
[0059] The loss on ignition of fly ash refers to the weight percentage lost after the fly ash burns at 1000-1100°C;
[0060] ②Technical indicators of quicklime: Active CaO accounts for 58% of the total mass of quicklime; digestion speed: 20min; digestion temperature: 56°C; quicklime fineness: 13%,
[0061] Digestion refers to the process of reaction between quicklime and water. When measuring the digestion speed and temperature, let 10g of quicklime react with 20mL of water, and record the time and corresponding temperature every 30s. The time taken for the temperature to rise to the h...
Embodiment 2
[0086] The present embodiment preparation method is the same as embodiment 1, and process parameter is as follows:
[0087] Fly ash: fineness: 32.5%, loss on ignition: 3.6%
[0088] Quicklime: active CaO content: 56.3%, digestion speed: 18min, digestion temperature: 53°C, fineness: 10.8%;
[0089] Pulping moisture content: 37.6%, pulping diffusion: 21cm;
[0090] Pouring temperature: 48°C.
[0091] The raw material ratio that present embodiment adopts is as follows:
[0092] Fly ash: 2025kg
[0093] Quicklime: 540kg
[0094] Cement: 54kg
[0095] Desulfurization gypsum: 81kg
[0096] Aluminum powder: 27kg
[0097] The resulting finished product has a compressive strength of 4.5MPa and a dry density of 620kg / m 3 , in full compliance with the requirements of the national standard B06 A3.5 grade qualified products.
Embodiment 3
[0099] The present embodiment preparation method is the same as embodiment 1, and process parameter is as follows:
[0100] Fly ash: fineness: 34.7%, loss on ignition: 3.8%
[0101] Quicklime: active CaO content: 61.5%, digestion speed: 22min, digestion temperature: 58°C, fineness: 12.1%;
[0102] Pulping moisture content: 38.2%, pulping diffusion: 21cm;
[0103] Pouring temperature: 48°C.
[0104] The raw material ratio that present embodiment adopts is as follows:
[0105] Fly ash: 2079kg
[0106] Quicklime: 513kg
[0107] Cement: 46kg
[0108] Desulfurization gypsum: 62kg
[0109] Aluminum powder: 25kg
[0110] The resulting finished product has a compressive strength of 4.1MPa and a dry density of 613kg / m 3 , in full compliance with the requirements of the national standard B06 A3.5 grade qualified products.
