Performance of Pozzolanic Concrete Using Different Mineral Admixtures
Concrete is probably the most extensively used construction material in the world. However, environmental concerns regarding rapid consumption of natural resources and CO2 emission during cement manufacturing process have brought pressure to reduce cement consumption by the use of cement replacement materials (CRMs). The utilization of calcined clay (metakaolin) and silica fume in concrete has ...
متن کاملPermeability of Concrete with Recycled Concrete Aggregate and Pozzolanic Materials under Stress
The research reported herein studied the permeability of concrete containing recycled-concrete aggregate (RA), superfine phosphorous slag (PHS), and ground granulated blast-furnace slag (GGBS) with and without stress. Test results showed that the chloride diffusion coefficient of RA concrete (RAC) without external loads decreased with time, and the permeability of RAC is much lower than that of...
متن کاملEco-Friendly Hybrid Concrete using Pozzolanic Binder and Glass Fibers
Hybrid Concrete focused on the development of buildings, highways, and other structures of civil engineering. In the current study, various mix combinations have been prepared and tested with different percentages of super-plasticizer at different levels of water reduction for obtaining the optimum mix. Further, study on different properties of hybrid concrete and replacement of ordinary portla...
متن کاملEffects of Waste Bricks Powder of Gachsaran Company as a Pozzolanic Material in Concrete
The aim of this study is to investigate the feasibility of using waste bricks powder of Gachsaran Company in concrete. Cement is replaced by waste bricks powder in different proportions until 40 percent by weight. pozzolanic properties of bricks powder and compressive strength of concrete were investigated. The results demonstrated that the bricks powder show pozzolanic properties. Results also...
متن کاملChemical concrete machine
The chemical concrete machine is a graph rewriting system which uses only local moves (rewrites), seen as chemical reactions involving molecules which are graphs made up by 4 trivalent nodes. It is Turing complete, therefore it might be used as a model of computation in algorithmic chemistry.
