Abstract

Formwork is the temporary moulds in the construction which are fabricated based on drawing and design of the structure and into which the concrete is poured to form the required structure. Formwork is an essential part of the construction as it has been in used by the Romans. The formworks must be strong enough to withstand all types of the loads. The joint must be in proper conditions to avoid any kind of leakages. The materials used for the formworks should be economical, easily available and durable. The formworks can be made up of different materials such as plywood, steel, aluminum, composite material etc. In Steel formwork the plates used for the slab support are made up of galvanized steels and these are fabricated as per the requirements. Aluminum plates are used in the aluminum framework along with the other components made up of aluminum. The selection of the suitable framework is important in any project because it bears about 25 to 30% cost of total cost of construction. In the present study, different types of formworks such as steel, plywood and aluminum were studied in a project and a comparison was made on the reusability and easiness in handling and maintenance. Also, comparison for the formwork used in construction of 5th and 11th floor tower based on the specific plan and drawing was done. The results showed that the aluminum formwork was found to be efficient and suitable among all formworks, although the cost was higher compared to other formwork’s materials.

Impact of Polymer Coating on the Flexural Strength and Deflection Characteristics of Fiber-Reinforced Concrete Beams DOI:  https://doi.org/10.30564/jbms.v4i2.5304 Abstract Liquid polymers (LP) have become an important structural material used in the construction industry in the last decade. This paper investigates the viability of using commercially available LPs as a coating material to improve the flexural strength of fiber-modified concrete beams. The scope included preparing rectangular prism concrete beams with a concrete mixture including fly ash and fiber and coating them with four different liquid polymers at a uniform thickness following the curing process while one set of samples was maintained under the same conditions as a control group without coating. In addition, cylindrical samples were prepared to determine the compressive strength of the concrete mixture. Following the curing process in an unconfined open-air laboratory environment for another 28 days, concrete sample

Achieving Sustainable Use and Management of Water Resources for Irrigation in Nigeria DOI:  https://doi.org/10.30564/jees.v2i2.2505 Abstract Water resource is available in Nigeria to meet water demand for domestic, agricultural and industrial use. If well enhanced and protected from various source of pollution. However, less information is available on suitability of water resources for irrigation use in Nigeria. This article reviews literature of the past with regards to influence of geogenic and anthropogenic activities on water resource for irrigation purpose in Nigeria and also to explain the current state of suitability of water resource for irrigation studies in Nigeria and gaps in studies. It also summarizes future ways on water resource management and preventive measure for water resource pollution for irrigation use. Related articles were downloaded from Google scholar in water-related issues. This paper tends to review previous article on water resource in Nigeria, and its su

Quality Models for Open, Flexible, and Online Learning DOI:  https://doi.org/10.30564/jcsr.v2i4.2357 Abstract This article is based on research conducted for the European Commission Education & Training 2020 working group on digital and online learning (ET2020 WG-DOL) specifically regarding policy challenges, such as the following: 1) Targeted policy guidance on innovative and open learning environments under outcome; 2) Proposal for a quality assurance model for open and innovative learning environments, its impact on specific assessment frameworks and its implication for EU recognition and transparency instruments. The article aims to define quality in open, flexible, and online learning, particularly in open education, open educational resources (OER), and massive open online courses (MOOC). Hence, quality domains, characteristics, and criteria are outlined and discussed, as well as how they contribute to quality and personal learning so that learners can orchestrate and take re
