Effect on consistency and performance of POFA concrete
The workability of fresh concrete properties was evaluated using slump test and flow table test and the performance of the hardened concrete was confirmed by cube compressive strength test at 3, 7 and 28 days. Based on the result, 5% POFA replacement using liquidation technique showed more workability compared to 10% POFA replacement.
Concrete Admixtures Archives - The Constructor
High-early-strength concrete can be developed using ordinary concrete constituents, special admixtures, and certain concreting practices. The high-early-strength concrete, which is also called fast track concrete, gains its specified strength at an early age compared to ordinary concrete.
Improved fired clay brick compressive strength by
This study investigates the effect of using steel filings from the waste of blacksmiths workshops on the clay bricks mixture to improve the bricks' compressive strength. On the other hand, this process can reduce workshops' waste by recycling it to preserve the resources and achieve sustainability. Adding steel filings to the mixture of red clay bricks was in different proportions by

Water Reducing Admixture for Concrete - Kingusn Chemicals
It is a concrete admixture that can reduce water consumption while the concrete slump is basically unchanged. As a concrete additive, water reducer for concrete plays a very important role in concrete applications. For example, the use of water-reducing admixtures can reduce the amount of water and increase the strength of concrete.

Cross-Layer Leaching of Coal Fly Ash and Mine Tailings to
Coal fly ash can be used in in various configurations (e.g. as cap, bottom liner, or blending) at a mine site, but comparative studies investigating their capacity to control acid mine drainage are limited. Batch and column leaching experiments were conducted to investigate the effects of fly ash-mine tailings mix ratios and system configurations on leachate chemistry. Acidic mine tailings (pH
concrete admixture for quick setting
Concrete Admixtures Types and Functions Cement . 02/02/2020 Concrete admixtures have various functions and they are as follows: (a) To increase the rate of strength development at early ages – calcium chloride is the most widely used accelerator, (b) To retard the initial setting time while pumping concrete over a long distance,
