- for manufacturing of cement using -
  (a) calcarious material like limestone,chalk etc.
  (b) argilacious material like clay or shale etc.
calcarious and argilacious
above ingradients are mixed in 2:1proportions and after the fine grinding . it is heated at 1400-1500°C .
after burning we get the cement clinkers Now it is mixed with zypsum and using the process -
1. Dry process.
2. wet process.
- Dry process is economical as compared to the wet process.

Design of RCC cantilever beam

step-1   Compute depth of beam  :-                 L eff. / d  = 7              d=effective depth.                     D=d+(ⲫ / 2)+cover    ⲫ= dia of bar         generally , in case of cantilever beam moment is varied and at free                end  its value is zero , so we reduce the depth of beam at free end.         if we take an example then if 400mm depth at fixed end then at free         end provided 200mm.  cantilever beam design : step-2   loading and moment calculate & check the depth  -                 M=0.36f ck bx u (d - 0.42x u )        M= Factored moment                                                                                   b= width of beam                                                                                   d= depth of beam required                                                                                   x u = neutral axis if depth is ok then continue. step-3 compute steel  -        M= 0.87f y A st (d - 0.42x

- In this article, we are discussed about "manufacturing   process of brick." first of all, we are talking about 'site   slection for manufacturing of brick.' Site slection for manufacturing of brick - - for manufacturing of brick , the following point should be   kept in your mind - (a) the ground should be levelled. (b) the available clay in this area should be pure. (c) any communicating facilities like roads should be     connected at site. (d) For labour, at least some facilities should be available,      like water, foods material or etc. site for brick manufacturing: Manufacturing process of brick - - the following steps should be used for manufacturing using   step by step - 1. Preparation of clay. 2. moulding of brick 3. drying of brick 4. burning of brick 5. Cooling of brick 1. Preparation of clay - -  the following process are used for preparation of clay-  (a) unsoiling  (b) digging  (c) cleaning  (d) weathering  (e) blendin
