Concreate - Assignment ExampleThe study also runs into consideration, the different types of Portland cement from type I to V. In the concrete mix preparation, the strength and uniformity of the concrete will be measured. This will enable the engineers to do necessary adjustments to regularize the range of strengths and elasticity.From the observations made in the general properties of the concrete mix, it is necessary to take note of the troweling feasibility of using the concrete. In order to ascertain determine whether the troweling is workable or not, the property test will require working with a trowel on the concrete. The quality of the concrete is measured by how smooth it was to work on it. If it requires so much strength to work on and then the trowel workability is troubled, and will be assigned either fair or poor rating. The concrete is produced in different layers, each layer containing unique motif of materials. The third layer is overfilled for the sake of consolid ation. The final stage is to finishing the upper layer using the tamping rod as well as the trowel to fine-tune it. This is then followed by covering the upper layer to ensure there is no evaporation. Temperature and moisture require careful treatment and observation since they directly mask the strength of the concrete. Before compressing and testing the concrete, one has to take the measurement of the radius and the diameter of concrete using calipers. The cylindrical concrete is measured in the middle at 4 points on its circumference. Just prior to the testing and compression, the engineers cap each end of the concrete to allow uniform spread of lading when a load is applied to it.Concretes are made into different shapes and compression failure modes to strengthen them. The shapes include full shear, change integrity (columnar), shear cone, cone splitting and local shear wedge. The variables to
