The materials required for the production of the concrete blocks are aggregates, cements and water. The aggregates of various types have been used with varying degree of success and they include crushed stones, gravel, volcanic cinders, ed slag, furnace clinker, etc.The aggregates are selected by considering the weight, texture or composition of the unit designed.

2. how many blocks can i get out of 1 trip of sand. 3. which type of sand is better for block molding. thanks I won't advice you to go for mass produced blocks, most guys doing mass production molded 50blocks using 1 bag of cement (dangote ordinary cement) now adays, due to dangote X3 cement, they mold 65 blocks which is barely able to give ...
Jul 08, 2020· 1500 pieces of 9x9 blocks @ 150 per 1 = #225,000 2 trucks of sharp sand @ 25,000 per = #50,000 20 bags of cement @ 1800 per 1 = #36,000 Digging wont cost you more than #30,000 will get you three coaches with some little blocks remaining. You can leave the space for the pillars since it cant be filled until the entire 10 coaches has been done.
225mm sandcrete hollow blocks are N1, 440.00 and N1, 648.08 respectively, while that of clay cement stabilized block is N1, 682.45 per square metre. The study recommends a reduction in the cement/sand and cement/clay mix ratios employed for both sandcrete hollow blocks and cement stabilized clay bricks to ratio 1:8 or 1:7 to enable

bukkyshobajo:. DANGOTE cement is not a portland cement even though it says that on the label, it has a rapid setting time and this makes it unsuitable for concrete work that requires curing of up to 28 days for it to attain it's maximum strength. it is however suitable for making blocks, laying blocks, tiling and plaster work at the proper mix ratio of 1:6 cement to sand.
Aug 17, 2018· Total Volume of Mortar Required for Laying 1m² of Block = 0.0159 + 0.0101 = 0.026m³. Therefore the volume of mortar required to lay one square metre of 9 inches block (with hole) can be taken as 0.026m 3 for all practical purposes.. let us assume that we have 100m 2 of wall, and we want to estimate the quantity of cement and sand for mortar needed to lay the blocks.
in concrete ingredients in the state of partial replacement. Sequentially, the shortage of river sand is partially rectified by the replacement of sawdust for the sand. So, the river sand abundantly gets destructed due to the huge consumption. To enhance the progress of river sand, we prefer a scope on saw dust concrete.
