What Is Ready-Mix Concrete? Advantages, Disadvantages and Uses Ready-mix concrete (RMC) is concrete that is produced in a batching or mixing plant according to a specified mix design and delivered to the construction site in a fresh condition , usually using transit mixer trucks. Unlike concrete mixed manually or in small site mixers, ready-mix concrete is produced under controlled conditions and supplied to the project when required. RMC is widely used for buildings, bridges, highways, foundations, slabs, columns, industrial structures, and infrastructure projects . How Is Ready-Mix Concrete Produced? The typical RMC process is: Raw Materials → Batching → Mixing → Transportation → Site Testing → Placement → Compaction → Finishing → Curing The main ingredients are: Cementitious materials Fine aggregate Coarse aggregate Water Admixtures, where required The quantities are controlled according to the approved concrete mix design. Types of Ready-Mix Concrete RMC can be supplied in differe...

What is Retaining wall in Construction?

Image
A Retaining Wall is a structure designed and constructed to resist the lateral pressure of soil when there is a desired change in ground elevation that exceeds the angle of repose of the soil. The basement wall is thus one form of retaining wall. However, the term is most often used to refer to a cantilever retaining wall, which is a freestanding structure without lateral support at its top Typically retaining walls are cantilevered from a footing extending up beyond the grade on one side and retaining a higher level grade on the opposite side. The walls must resist the lateral pressures generated by loose soils or, in some cases, water pressures. The most important consideration in proper design and installation of retaining walls is to recognize and counteract the fact that the retained material is attempting to move forward and downslope due to gravity. This creates lateral earth pressure behind the wall which depends on the angle of internal friction (phi) and the cohesive strengt...
