Prediction of the Granular Materials Strength
Prof. Saad Issa Sarsam

DOI : 10.36348/sjce.2020.v04i04.002
California bearing ratio (CBR) is an important property used to express the quality and strength of the unbound granular materials. Moreover, it is one of the material inputs for the empirical pavement design procedure. CBR is also conducted on the unbound materials for the quality control/quality assurance during construction. Because of its importance, this paper presents a mathematical approach to the problem of estimating the strength of local sand-aggregate material usually obtained from riverbed and banks and used as subbase layer for road construction. Based on simple and easy to determine physical parameters such as particles size distribution, modified proctor dry density (MDD), and moisture content, such estimation could be determined. The study can help in understanding the nature and the properties of sand-aggregate mixture and provide a reasonable and simple statistical method for assessing the strength from simple physical tests, and assist in considerable reduction of the bulk testing of samples on a project, thus affect economy, choice of material and quality control. The model obtained is capable to explain 73% of the variation in log CBR predicted from gradation and density parameters.

The Use of Polynomial Deflection Function in The Analysis of Thick Plates using Higher Order Shear Deformation Theory
In this work, polynomial deflection expression was used in the free-vibration investigation of thick rectangular plates with two different boundary conditions; one with its four edges clamped denoted with the acronym (CCCC) and another with two adjacent edges fixed and having simple supports at the other two adjacent edges denoted with the acronym (CCSS). The edge conditions of the various plates were fulfilled and used in generating the stiffness coefficients which were substituted into the analytical equation to obtain the non-dimensional frequency functions for the plates at different span-depth ratio (a/t) and aspect ratio (b/a). It was observed that at the same value of (b/a), there is an increase in the value of the non-dimensional frequency parameter as (a/t) increases. Also, at the same value of (a/t), there is a decrease in the value of the non-dimensional frequency parameter as (b/a) increases. The results obtained for the all edges clamped plate were compared with similar works by other researchers in the literature and were found to follow similar pattern and trend and were quite close.

The efficacy of hydrated lime (HL) as a flocculating agent in water treatment was studied in this work. Two water samples were used. Sample A was obtained from domestic sewage from Hostel A at the Federal University of Technology Owerri. While, sample B was sourced from storm water runoff from drains in Eziobodo Town, Owerri, Nigeria. The samples were treated separately using HL and sodium hydroxide (NaOH) as flocculants respectively. Alum (Al2SO4)3 was used as the coagulating agent for all samples. The jar test was adopted. Treated samples were analyzed for pH, color and turbidity. It was noted that addition of HL and NaOH in all samples increased the pH of the water. pH values for sample A and B were 2.7 and 4.1 before treatment and increased to values between 6.9 to 7.2 after treatment. The use of alum and HL in treating both samples of water led to better color quality than using alum and NaOH. Sample B water treated with HL had lesser color quality than those of sample A. The best color quality of 1.0 PCU happened when treating sample A water using 25mg/l alum and 43.8mg/l HL. Treatment of sample B using alum and NaOH did not improve turbidity. Rather, a maximum increase of 1.8% was observed at 25mg/l alum and 17.0mg/l NaOH dosage. The use of alum and HL showed a remarkable improvement in turbidity. Best value of 3.12NTU was measured at 25mg/l alum and 43.8mg/l HL dosage. Treatment of sample A with alum and HL gave better turbidity values when compared to sample B. Removal efficiencies of 95% and 90% for both samples were observed respectively. In conclusion, HL can be effectively used as a flocculating agent in treating water when applied in the right proportion.

The research work examined the modification of expansive soils with bagasse fibre to improve its engineering properties for road pavement structures. Preliminary investigations classified the clay soils as A – 7 – 6 on the AASHTO Classification System and soils are dark grey at all conditions and percentage (%) passing BS sieves #200 are 73.85%, 67.38%, 6.35%, 82.35%, and 71.55%. Comparative results confirmed a decrease in plastic index properties of clay soils. Compaction test results showed a decreased in MDD values while OMC recorded increased values due to bagasse fibre inclusion. Results obtained showed an increase in UCS with an increase in fibre percentages to soil corresponding ratio. Relative results showed an increased in CBR values with an increase in bagasse fibre percentages to a peak ratio of 0.75% to soil ratio. The entire results showed the potential of using costaceae lacerus bagasse fibre (CLBF) as admixtures in the treatment of clay soils. The swelling potential of treated soil decreased with the inclusion of bagasse fibre up to 0.75%.

This paper highlights the review of the behavior and strength of strengthening reinforced concrete columns by reinforced concrete jacketing. Even with the fact that on a massive scale, numerous experimental studies on column strengthening with the assistance of reinforced concrete jacketing are performed after which suggested, however, there may be nonetheless an apparent need for locating and executing new approaches to improve the performance of classical RC jacketing. As in the case of RC structure, columns are subjected to uniform and non-stop loading, which increases with the boom in a number of stories and might cause partly damage or even general failure of the column. To overcome the whole failure of RC columns, instant attention is needed in and the broken part of reinforced concrete repaired by way of reinforced concrete jacketing. This paper additionally focuses on the effect of presenting dowel rebar by way of drilling holes and using concrete jackets made with particular types of concrete. The results show that each use of dowel rebar and distinctive kinds of concrete will increase the bond strength, basic load wearing capability, and primary crack load. Critical cases clarified to avoid such as reinforcing limit and form, type and property of concrete, types of surface preparation, and a recommendation for high temperature.

DOI : 10.36348/sjce.2020.v04i01.001
This paper highlight, the techniques used to analyses symmetric structures subject to general loading. After an extensive review of previous work in this field, the paper introduces the most public way of structure analysis, based on conventional three methods which is force, matrix stiffness and column analogy techniques. It shows how this approach can systematically simplify a structural analysis and clarify a technique which is best known to structural engineers. For each method, a portal symmetry plane frame considered for analyzing with an explanation of the analysis calculation procedure, and it also shows that the influences of symmetry can observe and utilization in different methods to simplify the analysis procedure.
