This article is a study of articles getting pressure solder block and see our range of waterproof bonding block. With the separation of mixed size sand comes out clearly, whether it is a coarse grain type. 3. number of sand grains by using each source is resized as in case 3 mix is over 40, i. Burton, i. Burton, holding 4, Burton, i., i. Burton, back 40, through 200 mesh sieve and 4 200 telephone helpline open and mixing ratios in appropriate quantities and test.Exams are getting pressure and the absorption of water in the age of 7 days and 14 days curing from experimental results that are obtained through pressure, i. Burton, Ron, sand-based 4-40 make up is the ultimate strengths and water absorption of a lump sum, for example, found that the water absorption values of the sand source Ron Burton, i. 4-40 is the percentage water absorption and minimal water absorption values most. The quantity of sand is sand pellet making the minimum pressure is being received. The value and volume of water from rain, sand, coarse sand, which allows receiving the pressure is greater. There is little water absorption values.
