Abstract: The black cotton soil is known as expansive soil due to its property of swelling and expansiveness with influence of variance moisture in soil. It also shows shrinkage behavior when dried. Due to these properties the strength characteristics are also affected adversely. The black cotton soil is also widely available in all around the world which leads us to wastage of land for construction uses to resolve this problem we can replace the expansive soil by non-expansive soil which is also a costly option so in this present paper we have stabilize a soil using waste material named marble powder which is a byproduct of marble industries. For the determination of properties, we have performed atterberg’s limit test, particle size distribution by wet sieve analysis, water content test, specific gravity test, OMC and MDD test on the sample of granite powder. We have mark a great improvement in engineering properties of black cotton soil by stabilizing it with 5%, 10% and 15%, of replacement by granite powder. It also gives large decrement in swelling and shrinkage behavior of soil.

Abstract: Use of deep beam in construction field saves money as well as increase the strength of structure. Reinforced concrete deep beams have very useful structural application such as piles-caps, water tanks and tall buildings. Addition of steel fibers gives good results to both load carrying capacity and increase the flexural strength of the deep beam. Steel fiber is kind of newly developed reinforced material for concrete widely adopted globally now a day, which features good performance in anti-crack, pressure resistance, anti-abrasion bending toughness, affinity with concrete, reinforcement for construction element component and lengthy service life. Thus by using the steel fiber reinforced deep beam with varying percentage of steel fibers increases the first crack load and the ultimate load which gives the high flexural strength to the structure and achieves economy. This paper includes study of behaviour of steel fiber reinforced concrete in deep beam with advantages, disadvantages, properties of steel fiber etc.

Keywords: Steel Fiber, Beam, Anti-Abrasion Bending Toughness, Affinity, Reinforcement.

Abstract: In this study, integral calculus has been applied to the beam analogy method for the evaluation of the non-dimensional frequency parameters of isotropic functionally graded (FG) rectangular plates resting on Winkler elastic foundation. The fundamental assumptions of linear, elastic, small-deflection theory of bending for thin plates due to Kirchhoff are taken into consideration. Using direct integration, characteristic orthogonal polynomials (COPs) shape function for all-round clamped (CCCC) plate is formulated. The effect of aspect ratios on the natural frequency of the plate is examined. It is evident that adding an elastic foundation increases the non-dimensional frequency parameter of the plates. Furthermore, like plates resting on Winkler foundation, an increase in aspect ratio, causes a corresponding increase in frequency for plates not subjected to the effect of Winkler elastic foundation regardless of the boundary configuration. Hence, fixity of supports increases the fundamental natural frequency of the plate, and so increases the resistance of the plate to higher forcing frequencies before resonance can occur. It is also observed that an increase in power law index decreases the frequency parameters of the plate. The validity of the present theory is investigated by comparing some of the present results with those reported in the literature. It can be concluded that the proposed theory is accurate and simple in solving the free vibration behavior of FG plates.

Keywords: Winkler foundation, vibration, functionally graded plate, rectangular plat, characteristic orthogonal polynomials.

Abstract: This paper investigates the effect of polypropylene fibers on slump flow of self-compacting lightweight concrete. The water/binder ratio that was used in concrete mixes was set to 0.4. four mixes with different proportions of Polypropylene fibers were prepared and adjusted by inserting micro-silica and fly ash as supplementary cementitious materials. The percentages of micro-silica and fly ash were fixed to have the values of 5% and 20%, respectively. The replacement ratios of Polypropylene Fibers were from 0% up to 0.4%. The graduation, specific gravity, water absorption, and fineness modulus have been testified for two types of local fine aggregates, in addition to, the graduation, specific gravity, water absorption, particle shape, and surface texture of lightweight scoria coarse aggregate. the relationships between the proportions of fibers and slump flow of fresh concrete have been identified as well.
