To increase the floor area vertically, we need a floor plate, which is also known as the no. Make or concreting not be done with conventional methods using cast concrete and fabrication.
Formerly know an area of the floor slab to be casted. The area not more than 3m x 3m should use joist. Plate floor using joist cornya minimal thickness 12cm, 15cm thickness while those not. Here are the things you need to look before concreting.
Composition of Concrete
Nothing concrete for structural work and non-structural. For non-structural, such as concrete quality B0, the volume of sand: gravel / rock breakup not to exceed 8:1.
The ratio of water to cement is usually 10-20%, calculated based on the weight of cement used. Excess water can cause cracks in the concrete after it has dried. Water that does not evaporate and react join form pores. This will affect the strength of concrete produced. This is one reason that the foundry did not to do when it rains, except where casting protected from water.
