Its all depends on the quality want to produce. For a good standard quality below combination of ration 1. Mix Proportion For Fly Ash Bricks manufacturing – (Here Hydrated Lime is used instead of Sludge Lime) > Fly ash – 57 to 65% River Sand or St

This has now been proven and a patent is taken for the manufacture of bricks from fly ash.7 The response of the ash to firing temperature at 1000o C and beyond can be accurately controlled even in small factories.

Fly Ash brick is a product of basic cement clinker materials i.e. fly ash, stone dust/sand, lime, gypsum and bonding agent. The mix is so ideally worked out to produce bricks of higher strength with consistency as well as uniformity. The manufacturing process is fully automatic with state of art technology.

Saving in cement 430-337 = 93 kg/m 3. It may be noticed that, for the fly ash concrete the total cementitious material is greater but the OP cement content is smaller, the fine aggregate content is reduced but the coarse aggregate content is deliberately the same, the water is reduced and the density is reduced because of the lower density of fly ash compared with cement.

2011-7-1 · fly ash in the present method will be a big challenge to environment, especially when the quantum increases from the present level. The proposed unite will be using both type of fly ash depends upon the availbality 4.a Characteristics of Fly ash The physical and chemical properties of Fly Ash are tabulated below 4.a. i. Physical Properties

2011-3-15 · Fly ash is a by-product of the combustion of pulverized coal in electric power generating It is the most widely used supplementary cementitious material in concrete. It is used in more than 50% of ready mix concrete. The replacement level of Class F fly ash its chemical composition and physical properties are provided in Table 1 and 2.

However it is also used to make quality fly ash bricks. 2. Mixing ratio for fly ash bricks. Fly ash (57-65%). River Sand or stone dust (18-27%). Hydrated Lime (9-12%). Gypsum (5%). NOTE:- Fly Ash Bricks Mixing Formulas, This is widely used mixing ratio to make quality fly ash bricks. Hydrated lime is easily available.

2015-1-3 · In this paper, experimentally investigated the fly ash brick mix proportions by Taguchi method. Least quantity of cement and fly ash has been used as binding materials and considered the control factor as water binder ratio. Both. So the effects of water/binder ratio, fly ash, coarse sand, and stone
