Is using GGBS in concrete more expensive?
Using Ground Granulated Blast Furnace Slag (GGBS) in concrete can be more expensive than traditional Portland cement due to the higher cost of the material and the processing involved. However, GGBS can enhance the durability and longevity of concrete, potentially leading to lower maintenance and lifecycle costs. Additionally, its use may be incentivized by sustainability goals, offsetting initial costs over time. Ultimately, the economic impact depends on project specifications and local material availability.
How much does a cinder block foundation cost?
Beijing trinity trade 100,000 /m3 Foamed Concrete Production Line http://www.foamed.com.cn 1. Advantages 1) Small investment - investment can vary from 300 thousand to 5 million. The cost of this foamed concrete production line is only 1/3-1/10 compare to aerated concrete production line when production is the same scale. (Chinese Yuan is used whenever applying to price.) 2) Energy conservation - No steam pressure in production is needed, unless quantity of fly ash or sand reaches to 70% of the ratio. 3) Able to produce low density products, such as ultra light products that its density is 200-400 kg/m3. 4) Less investment - Investment is only 1/20 of aerated concrete; good mobility and easy to assemble 5) Dry cutting - This sawing machine adopts dry cutting sawing blade, and it no residue shall be left after cutting. Meanwhile, this sawing machine costs only 100 thousand, therefore, lower total cost. By adopting bamboo plywood mould, its investment is only 1/2o of aerated concrete. 2. Major Raw Materials 1) Cement - Ordinary Portland cement 42.5 N is widely used. (PO42.5), or grade 32.5 N. Do not use Portland blast furnace slag cement (PS) Portland composite cement (PC) fly ash cement (PF). 2) Sand - clean river sand is recommended, otherwise dirt of sand has to be less than 2%. 3) Active residue. Residues from coal, steel, and minerals, such as fly ash and steel slag. 4) Addition agent (accelerator) - stabilize, anti-shrink, accelerate, and enhancefoam; only 1%-2% of cement quantity when use. 5) Foaming Agent- 0.5-1kg every square meter. It is one of Trinity Trade's products. 3. Cost This cost is not a definite number, because it depends on density, raw materials, ratio, and techniques; however, we have some reference value as following. 1) Total cost when density is 600kg/m3 Raw materials Quantity (kg) Cost (yuan) Total (yuan) cement 330 300 yuan/ton 99 Sand 165 40 yuan/ton 6.6 Fly ash 35 100 yuan/ton 3.5 Chemically combined water with cement 65 kg roughly o Foaming agent cost 9 yuan per 0.7 kg o Addition Agent 6 kg×5 yuan ≈30 yuan (not necessary in summer) o Labor, electricity, depreciation, and administrational and sales expense cost 20 yuan/m3 Therefore, total cost is approximately 168 yuan/m3 2) Total cost when density is 300 kg/ m3 Raw materials Quantity (kg) Cost (yuan) Total (yuan) Cement 166 300 60 Sand 84 40 3.3 Fly ash 18 100 1.8 Chemically combined water with cement 33 kg roughly o Foaming agent: 1kg costs 13 yuan o Addition Agent: 3kg costs 15 yuan (not necessary in summer) o Labor, electricity, depreciation, and administrational and sales expense cost 20 yuan/m3 Total cost is approximately 113.1yuan/ m3 4.
