I have a floor area of 4meter x 2meter to lay tiles. How do I calculate how many bags of 50kg cement do I need?
you're able to calculate the quantity of your floor assume a a million sq. meter section and assume the thickness is .3 mm (not .2) the quantity could then be = 0.0003 m x a million m x 1m = 0.0003 cubic meters Volumetricly, you elect for a million/4 area concrete + 3/4 components sand to equivalent 0.0003 cubic meters. The concrete quantity could then be 0.000075 cubic meters concrete consistent with a million sq. meter of floor (at .3 mm thickness).... or seventy 5 cubic centimeters consistent with squaremeter The density of Portland cement is approximately 3 g consistent with cubic centimeter consequently 3 g/cm3 * seventy 5 cm3 = 225 grams or 0.225 kg of cement consistent with sq. meter of floor
You don't need cement at all. Ceramic tile is installed using thinset mortar. There are several types depending on the particular type of tile and the substrate you will cover. Additives are recommended for certain situations. The tile manufacturer should have a recommendation for mortar type and additives, if needed. Mortar coverage is given as a range, and each manufacturer will state that range on the bag. A typical sanded mortar will cover 0.3 to 0.4 square meters per kilogram. A 50 kg bag will cover 15-20 square meters, so only about half a bag would be required to do an 8 square meter area. Mortars are often packaged in multi-wall bags that include a plastic layer to reduce the infiltration of water vapor. Mortar, like any cement-based product, will absorb moisture from the air and degrade over time. Two layers of plastic bags tightly sealed with twist ties will keep leftover mortar fresh for future projects.
