Aug 01, 2009 Effect of copper slag substitute on the workability and density of HPCThe effect of copper slag replacement as fine aggregates on the workability and density of high performance concrete is presented in Table 2 for different proportions of copper slag. The workability of concrete was assessed based on the measured slump of fresh concrete.
Effects of Copper Slag as a Replacement for Fine Aggregate . Effects of Copper Slag as a Replacement for Fine Aggregate on the Behavior and Ultimate Strength of Reinforced Concrete Slender Columns used Table 2 shows the mix design quantities The mix constituents were weighed in separate buckets and mixed in a rotating drum in accordance with the American Society for Testing and
5. It is recommended that 40 wt% of copper slag can be used as replacement of sand in order to obtain HPC with good properties. 6. It should be noted that further research work is needed to explore the effect of copper slag as fine aggregates on the properties of concrete with different cement types, silica fume sources and the degree of fines.
Abstract: This research studies the use of waste copper slag as a cement replacement in high-performance concrete (HPC). To obtain two level of fineness, the copper slag was milled using a ball mill. A mixture was prepared with different percentages of copper slag ranging from 0% to 40% in steps of 10%. To obtain the
The effect of copper slag addition as replacement of fine aggregate on the density of normal and high strength concretes is shown in Fig. 1. It can be seen from Fig. 1 that there is general increase in the density of both normal and high strength concretes with the increase of copper slag replacement

Re: calculation of false air entry in coal mill. You can use: 1. Mass balance. 2. Heat balance. 3. Oxygen balance (oxygen correction) easiest is Oxygen balance that you measrue oxygen going in and out and do oxygen balance base on this formula: V2 = Vt (21-Oout)/(21-Oin) V2 = false air valume. Vt = total volume (V1 + V2) Oout = Oxygen % in
false air calculation in cement plant . Water-to-Cement Ratio and Aggregate Moisture CorrectionsMay 28, 2010· Once general requirements such as the required compressive strength, air content and slump have been established, initial mix designs may be developed following the guidelines in ACI 2111, “Standard Practice for Selecting Proportions
False Air Calculation In Cement Plant. A typical concrete batch plant mixes water cement fine aggregate e.g. sand and coarse aggregate e.g. gravel and a small amount of supplemental materials in a very large drum to create concrete. 1 At most commercial-scale concrete plants the cement is stored
It is therefore important to know the points where false air can appear and to know the percentage of false air: in order to take appropriate measures. For that, some measurements are necessary on site. False air is mostly present in the following areas of a cement plant: * Raw mill grinding area * Kiln area * Cement mill grinding area –
