Abstract: A feasibility study was undertaken on the production of wade sand-natural hydraulic lime-cement-phosphogypsum (WS-NHL-C-PG) full bricks grade MW to build houses economically by utilizing industrial wastes. All full bricks were made on a bench model, semiautomatic press having a capacity of 25 tons to produce bricks of 51×95×203 mm in size under a static compaction of 27MPa.Tests were conducted to study behavior immersion of phosphogypsum- wade sand based bricks. The results suggest that these bricks have sufficient behavior immersion.

Abstracts: The study estimated total factor productivity for principal crops in Madhya Pradesh using time series secondary data on area, production productivity of major crops in Madhya Pradesh. The Malmquist model is selected over Tornqvist model for the study because of stationality and redundancy problem associated with time series. Structural changes occurred in area and production of principal crops during the specific period of time due to policy effect and autonomous production as well. The variability in the total outputs and total inputs index was due to exploitation of available production potential in the state. Malmquist total factor productivity index explained the stages of production in Madhya Pradesh over periods of time. Post global and combine periods were better as compared with pre global period. Total factor productivity is a comprehensive measure of productivity and has gained acceptance among government officers, policy makers, productivity specialist and economist.
