Abstract

This study measure the curing condition on the high Strength concrete durability in Bangladesh. In the industry of  construction, HPC (High Performance Concrete) has important role for improving durability and improved strength over ordinary concrete. Appropriate concrete compaction is essential for ensuring durability and strength of concrete. Entrapped air expels can placed concrete freshly and set the combined particles collectively that can increase the concrete density. Alike, concrete cover should maintain properly from environmental effects that can protect reinforcement such as deterioration and affords thermal insulation. concrete Durability refers to the ability of concrete to oppose abrasion, chemical attack and weathering action whereas maintaining its preferred civil engineering properties. This study observed that concrete made by clean water and under normal curing condition showed low permeability and Concrete mode by clean water and used within 2 hours showed moderate permeability. This study also showed than Concrete mode with polluted water gave high permeability. The present study will assist civil engineers and supervisors to know the impact of curing condition on the performance concrete durability.

 Key words: Curing condition, High Strength concrete, Durability, compressive strength, tensile strength & shrinkage.

A Review on the Potentiality of Derivative Market and Economic Stability of Bangladesh Author: Md. Edrich Molla

A Review on the Potentiality of Derivative Market and Economic Stability of Bangladesh

Author: 

Md. Edrich Molla

Abstract

This study uncovers the different prospects of derivative market in Bangladesh. Economic stability can be achieved through derivative market in Bangladesh. Due to instable economic conditions and restricted environment, corporate sector has reflected insignificant contribution in equity or bond markets in Bangladesh. Rapid infrastructure development, political stability, effective governance, experience and awareness of market participants are the key factors that may lead to build a strong derivative market in Bangladesh. Hence, literature is reviewed and analyzed due to unavailability of appropriate data for this study. Findings of the study have suggested that derivatives are an effective risk mitigating tool on one hand whereas on the other side, highly speculative activities in derivative market may be harmful for the financial markets and economic growth. In Bangladesh perspective, all the players of financial market will have to adopt adequate risk mitigating strategies to avoid any adverse market scenario. Speculative activities must be highly restricted due to economic instability as Bangladesh is not in a position to absorb any financial shocks or crisis. The main regulatory authority of this particular market will be Bangladesh Bank (BB) and Bangladesh Security and Exchange Commission (BSEC) though this kind of market is not introduced yet in Bangladesh. The regulators will keenly observe market and take necessary actions to prevent any adverse conditions.

 Key words: Bond Market, Economic Stability, Developing Economies, Bangladesh.

Abstract

A study was conducted to investigate the effects of feeding citric acid and acetic acid on live weight gain, feed consumption, FCR, meat yield traits of commercial broilers. A total of 108 day old broiler chicks (Cobb 500) fed diets T0, T1, T2 and T3 having three replications in each.T0 (Basal diet with no supplemental acid), T1 (Basal diet with 0.75% citric acid), T2 (Basal diet with 0.75% acetic acid) and T3 (Basal diet with 0.75% citric acid and 0.75% acetic acid).The birds were reared in cage management system. Body weight gains, feed conversion ratio (FCR), mortality and meat yield traits were recorded and analyzed in CRD by using the SPSS software. Feed intake (g/bird) was almost similar (P>0.05) among the dietary groups. Body weight gain (gm) and FCR were significantly (P<0.05) different among the dietary groups. The highest body weight gain (gm) was (P<0.05) in T1 (1512.37gm), followed by T3 (1496.30gm) and T2 (1470.40gm) and T0 (1325.47gm) respectively. The lowest FCR was found in T1 (1.40) and the highest FCR in T0 (1.52), the intermediate in T2 (1.43) and T3 (1.41) respectively. It was found that there was significant (P<0.05) difference among the dietary groups in case of carcass weight (gm).live weight (gm),thigh weight (gm), breast weight(gm) but there was almost similar(P>0.05) among the dietary groups for heart weight (gm), spleen weight(gm), gizzard weight(gm), head weight(gm) and intestine weight (gm). Carcass weight in T1 (905gm) and live weight T1 (1496.67gm) were significantly (P<0.05) different compared to control T0 (668gm) and T0 (1160.67gm) respectively. No mortality was found among the dietary groups during experimental period. It was concluded from this experiment that supplementation of 0.75% citric acid in the diet had positive effect on the performance of broiler production.
