The aggregates used will consist of sand, gravel, crushed stone, slag, cinders or other inert materials or combination of them. They must be free from excessive amounts of dust, soft or flaky particles or other deleterious materials; maturely sand without salt content is widely used but very cements consuming. The binding of aggregates is performed by cement, it is therefore logical that in the production of concrete blocks. The mixing ratio varies according to aggregate locally available. For trial purpose, the following is guidance: Take 400*200*200mm blocks as example Block Strength(Mpa) Cement (kg) Aggregates (kg) Quantity( 400*200*200) 7.5Mpa 100kg 1700kg 120pcs 10.5Mpa 100kg 1250kg 90pcs 15Mpa 100kg 1025kg 75pcs 22.5Mpa 100kg 800kg 60pcs 30Mpa 100kg 605kg 47pcs NATURAL CURING The ambient temperature (surrounding temperature) plays an important role in determining the speed of hardening process. The warmer the air, the warmer the concrete and the quicker the concrete strength gain. In countries where the climate is favorable, fresh blocks are most cured at normal temperature of 20℃ to37℃ (as in the South of China). This type of curing which at 4 days would normally give 40% of its ultimate strength. Initially, fresh blocks should be placed in a shaded area or enclosed chambers for about 8-12 hours (depends on relative weather conditions i.e. temperature, humidity etc). After that, the blocks can be transported to an assembly yard for further curing for about 28 days to reach 99% of its maximum strength. For optional final products, the fresh blocks need to be sprinkled daily, for the first 7 days (morning and evening) to maintain the moisture content for higher reactivity of cement with sand 28-days curing to gain the full strength of masonry product is based on concrete which is slightly different when applying for the dry mix material for the block making. It is very commonly now cement is added with high quality fly ash and under the favorable conditions like the temperature and humidity; the compressive strength of the block/ pavers will gain up to 80% in less than 7 days curing. By using the #425 type cement and design the mix proportional at least 20% higher than the required compressive strength (MPa), the blocks/pavers will be qualified to be delivered to the clients information Tel:+8+8
