Mix Design Development for Pervious Concrete In Cold Weather Climates
Portland cement pervious concrete (PCPC) is increasingly being used in the United States in sidewalks and parking lots due to its benefits in reducing the amount of runoff water and improving water quality. In the United States, PCPC typically has high porosity and low strength, which has resulted in limited use of pervious concrete in hard wet freeze environments (i.e., the Midwest and Northea...
متن کاملPermeability of Concrete Mix Design
In the present investigation, study of water permeability of concrete was carried out..The strength of concrete is depend on its mix proportions. we used high strength concrete which have its compressive strength is above 50 MPa.in order to measure co-efficient of permeability as per IS:3085-1965,the cylinder with height to diameter ratio equal to one were cast and subjected to a constant press...
متن کاملSelf-Compacting Concrete - Procedure for Mix Design
Self-compacting concrete is a fluid mixture suitable for placing in structures with congested reinforcement without vibration. Self-compacting concrete development must ensure a good balance between deformability and stability. Also, compactibility is affected by the characteristics of materials and the mix proportions; it becomes necessary to evolve a procedure for mix design of SCC. The paper...
متن کاملVirtual Pervious Concrete: Microstructure, Percolation, and Permeability
As the usage of pervious concrete continues to increase dramatically, a better understanding of the linkages between microstructure, transport properties, and durability will assist suppliers in mixture proportioning and design. This paper presents various virtual pervious concrete microstructural models and compares their percolation characteristics and computed transport properties to those o...
متن کاملValue of Admixture in Concrete Mix Design
Despite its few inherent shortcomings, concrete has proved to be the most widely used construction material, no substitute in time still to come. In the present investigation, study of admixture of concrete was carried out. The strength of concrete depends on its mix proportions. We used so many admixture e.g. ‘silica. Fumes, fly ash etc , when we used these type of admixture the result was ver...
