Deszifratu zementu-kopurua apar-hormigoian

What are the raw materials of apar-hormigoia?

The main components of foamed concrete are cement, errauts hegan, silize kea, zuntza, etab. Some proportions have more cement content, and some proportions have less cement proportions, so specific problems must be analyzed in detail. Because foamed concrete is mostly cured under normal temperature conditions, eta apar kopuru handia gehitzen da, these two factors determine that its cement ratio will be higher.

What is ALC?

ALC is the abbreviation of autoclaved lightweight concrete, which is a kind of high-performance autoclaved aerated concrete (ALC). ALC board is made of fly ash (or silica sand), zementua, karea, etab. lehengai nagusi gisa, and is cured by high-pressure steam to form a porous concrete sheet (containing processed steel reinforcement). ALC board can be used as wall material and roof panel. It is a new type of building material with superior performance. ALC board first appeared in Europe, and Japan, Europe and other regions have more than 40 years of production and application history. Gaur egun, the production technology and production equipment of domestic manufacturers are mainly imported from Japan and Germany.

Foam concrete is fundamentally different from ALC. Because ALC adopts autoclave, batez ere, errauts hegan eta karearen hidratazio-erreakzioan oinarritzen da bero eta presio handiarekin gelazioa sortzeko. Cement is an auxiliary material.

While foam concrete is produced at room temperature, the active microaggregate will not quickly produce hydration reaction, eta bere apar solidoa oraindik zementuaren zementu-efektuaren araberakoa da. Horregatik, the mixing ratio of foamed concrete must be cement as the main body, eta zementu ratio altua.

Egoera normaletan, the amount of cement should account for more than 30% material lehorren guztizko kantitatea, eta 30% should be the minimum use amount for its normal temperature curing. Gunean isurtzerakoan, zementu proportzioa baino gehiago izan beharko luke 60% material lehor guztien artean. Beheko dentsitatea duen apar-hormigoi tenperatura normaletarako 600 kg/m3, zementuaren proportzioa ez da baino txikiagoa izan behar 70% material osoaren. Dentsitatea azpitik dagoenean 400 kg/m3, the conventional proportion should account for more than 90% material lehor osoaren.

The following factors should be considered in the design of cement ratio:

(1) Zementuaren barietatea. Erresistentzia goiztiar eta berantiar handiko zementu motak (hala nola, Portland zementu dual-azkar) zementuaren proportzioa behar bezala murriztu dezake, and cement types with low late strength or low early strength should increase the cement proportion;

(2) Zementuaren erresistentzia-maila. High-strength grade cement (esaterako 42.5, 52.5, etab.) can reduce the proportioning amount, eta erresistentzia baxuko zementuak bere proportzio-kopurua handitu beharko luke;

(3) Zementuaren kalitatea. For large plants’ new dry-process rotary kiln cement, the mixing ratio can be appropriately reduced, while for small plants, shaft kiln cement or cement with a large mixing ratio should be appropriately increased;

(4) Density and strength requirements of the product. Dentsitate baxuko edo indar handiagoko eskakizunek zementu proportzioa handitu beharko lukete, dentsitate handiko edo indar baxuagoko eskakizunek zementu-erlazioa murrizten dute;

(5) Initial growth temperature. Isuri ondoren hasierako ontze-tenperatura (isurtzen) baxuagoa da (<25°C). The proportion of cement should be increased. When the initial curing temperature is high (25℃-45℃), the proportion of cement can be appropriately reduced. If steam curing or autoclave is used, it is still strong to reduce the proportion of cement;

(6) Variety and activity of active micro-aggregate (nahasketa). Aktibitate handiko mikroagregatuen erabilerak zementuaren proportzioa murriztu dezake (hala nola, zepa ultrafina), aktibitate baxuko mikroagregatuen erabilera, berriz (hala nola bigarren mailako errauts hegalariak) zementuaren proportzioa handitu dezake.
