Consturction Material EGC 1131 Assignment 1 Question 1 (a) A significant tendency for large and fine particles in a concrete mix‚ separate among each others. Segregation is caused by * Too wet mix‚ extremely high workability or less cohesive mixture causes the mixture unable to hold heavy aggregate * Dropping from excessive height * Over compaction of fresh concrete. Two methods to minimize segregation in fresh concrete: * Adequate workability is enough. * Don’t over

The M3 would take a lot of the positive aspects of the M2 and expand upon them‚ to the effect that our British allies would request support from America before we had officially entered the war. Over 4500 M3s would be produced with several different variants each having increased performance‚ armor or other mechanical advancements. Some of

However‚ one workable definition of ceramics is a refractory‚ inorganic and non-metallic material. Ceramics can be divided into two classes: traditional and advanced. Traditional ceramics include clay products‚ silicate glass and cement; while

vane six is multiplied by two since it is easier to rotate the vanes. From Table 1.0‚ the values for the undrained shear strength of the soil for the first trial using the medium vane‚ larger vane‚ and smaller vane are as follows: 18kN/m3‚ 17 kN/m3‚ and 19 kN/m3‚ respectively. It can be observed that the values are relatively large‚ this is because the soil sample is fully saturated. However‚ the results of each test using different vane sizes yielded different values. The differences in the values
