Building Layout. After finalising the building plan and design of the structural component, including foundations, the construction activity can be started.. After that, the first step in construction activity is site clearance. It was then marking foundation trenches which are going to be excavation lines which are marked on site is known as building layout.

· By the Standardconsistency test of cement, we can find that how much water is required to produce effective cement paste which will eventually produce good quality of concrete/mortar. The standard consistency of cement paste is used basically, in the determination of water/cement ratio, the setting time, soundness and compressive strength tests of cement.

Concrete Mix Design Process: How It Works. Before we get into how automation can help, let's take a highlevel look at a material producer's general approach to concrete mix design. Data is key. That's why the first step in the process is pulling information about raw materials and ingredients, which include:
