Categories: Aggregates, Concrete Technology, Consolidation, Mixture Proportioning. Formats: Online Learning. Table of Contents. Learning objectives: 1. Explain the interaction among concrete proportioning, workability, and the amount of required consolidation energy necessary to successfully place concrete in various forms. 2. Consolidation of concrete is the process of removing this excessive air and making the concrete into a uniformly solid mass with the needed properties. Consolidation also levels the fresh concrete and improves the bonding with the reinforcement.   Physics Procedia 25 () – © Published by Elsevier B.V.

This paper reports on the current state of the prime method used for consolidation of concrete, namely the vibration. In addition to a relative completeness, the main contribution of this paper lies in the unified, systematic organization of the presently available but scattered and sometimes contradicting findings on the vibration of concrete.

Self-consolidating concrete (SCC) is an advanced type of concrete that at the time of placement can flow and consolidate under its own mass without vibration, pass through intricate scientific study of flow. In the context of concrete, rheology provides a scientific description of workability. The rheology of concrete is quantified in terms. Concrete Basicsaims to provide a clear, concise explanation of all aspects of making quality concrete; from the Materials and Properties involved through Planning, Preparation, Finishing and Curing. Concrete Basicsaddresses the needs of unskilled and semi-skilled persons undertaking general concreting projects including home and handyman projects.

  Self-consolidating concrete (SCC) is an innovative material used successfully throughout the world. It is a highly flowable, non-segregating concrete that can spread into place, fill the formwork, and encapsulate the reinforcement without any mechanical consolidation, improving the overall efficiency of a concrete construction project.   Consolidating Concrete When concrete comes DOWN the chute and flows into forms it carries entrapped air (not to be confused with entrained air). If the entrapped air isn’t removed, it leaves holes in the concrete (HONEYCOMBS), especially next to form surfaces. Poorly consolidated concrete is more porous and REBAR is poorly bonded. consolidating concrete can be assessed by visually evaluating the distribution of the coarse aggregate within the concrete mass after the spreading of the concrete has stopped. Typically once the slump flow test has been completed, a visual stability index value is assigned to the concrete. For adequate consolidation of concrete, the desirable amount of air, water, cement, and fine aggregate (that is, the mortar fraction) should be about 50% to 65% by absolute volume (45% to 60% by mass). Rounded aggre-gate, such as gravel, requires slightly lower values, while.
