Exploring The Influence of The UK Construction Industry Players in Embracing Modern Methods of Construction

The ninth goal of the sustainable development goal (SDG) is to build resilient infrastructure, promote inclusive and sustainable industrialization and foster innovation while the eleventh goal is to make cities and human settlements inclusive, safe, resilient and sustainable. Despite these, there is still a wide gap between various governmental advances and the availability of homes and commercial property around the world, in Europe and most especially, in the United Kingdom. Hence, there has been a significant push for the Construction industry to embrace the use of Modern Methods of Construction (MMC) to alleviate the housing problems. However, notwithstanding the many benefits of MMC, there are still barriers to full implementation in the construction industry. This research therefore explores the understanding and the ability of the professionals in the UK construction industry to influence the adoption of this innovative construction method. This study is carried out through a combination of a literature review and a questionnaire survey of the top professionals in the UK construction industry. The result establishes that the construction professional’s understanding is appropriate in advising clients on the use and potential benefits of MMC. The findings then motivate a further investigation into other likely impediments hindering a full take-off of MMC in the UK

Performance of lateritic concrete under environmental harsh condition

This is an investigation of weathering characteristics of Laterized concrete with laterite-fine aggregate ratio as a factor. It was done with a view of ascertaining the suitability of laterite as aggregate substitutes at 0, 10, 20, 30 and 40% of fine aggregate used in the construction industry. The weathering characteristics were examined by conditioning laterized concrete cubes to varying temperatures, chemical and alternate wetting and drying, which all represent the operating weather conditions (wet and dry seasons) in tropics, including Nigeria. The mix proportion used was 1: 2: 4, the curing age of the laterized concrete was based on 28days curing age, while the compressive strength of the treated laterized concrete cubes was determined. The result of this research showed that the compressive strength of laterized concrete with laterite-fine aggregate ratio variation decreases when subjected to alternate wetting and drying and increases when subjected to magnesium sulphate (Mg2SO4). It was also discovered that a laterized concrete with a laterite-fine aggregate ratio of 20% conditioned to a temperature range of 100oC attained optimum compressive strength of 12.90 Nmm-

Comparative Analysis Of Portland Cements In Nigeria

Portland cement remains the most common type generally in use throughout the world as a basic ingredient of concrete. Five brands of Portland cement commonly available in Nigeria were investigated through series of tests conducted to determine their strength characteristics, setting time, soundness, workability and fineness among others and examined if they meet the minimum standard as stipulated by the British Standard Institute. Five brands of cement considered were Dangote, Elephant, Burham, Diamond and Purechem. The results show that all the brands examined meet the British Standard requirements on all the tests subjected to. Burham cement was fastest with initial setting time of 100 minutes ahead of other, while Dangote cement was the least with initial setting time of 180 minutes. The strengths characteristics of the five brands are similar with slight difference recorded. Dangote cement had the highest strength at 28th day curing period of 474 KN as the crushing load while the least strength was of Purechem at 370.6 KN as the rushing load

Effects of Precipitation Hardening Variables on Al–Zn–Mg-Sn Alloy as Sacrificial Anode in Seawater: Experimental and Statistical Analysis

This research investigated the effects of tin composition and heat treatment variables on the Al-Zn-Mg alloy as sacrificial anode in seawater using gravimetric technique and statistical analysis. Tin was alloyed with Al-Zn-Mg in varied proportions (0%, 0.01%, 0.05% and 0.1%) to determine the optimum anode efficiency in the marine environment. Precipitation heat treatment was performed by first subjecting the samples to solution treatment at 5380C for 2 hours and later subjected to varying hardening temperatures and times. The samples were hardened for 4, 8 and 12 hours at each of the hardening temperatures of 1300, 1600 and 1900 centigrade. The anode efficiency increases as the tin concentration increases. The experimental result of this study showed that the Al-Zn-Mg alloy with 0.1% tin gives the optimum anode efficiency. It was revealed that the Al-Zn-Mg alloy without tin composition exhibited high output current capacity when hardened at 1900C for 4 hours. Predictive model developed in this work was in consonance with experimental observation except the following; at hardening temperature of 1600C, the model recommended 12 hours as against 4 hours of laboratory experiment and at hardening temperature of 1300C it advocated 8 hours as against 12 hours

Pulverised Sewage Sludge Ash Partial Replacement of Cement In Concrete

The potential of the ash produced from the incineration of sewage sludge, as partial replacement of cement in concrete has generated research interest in recent times as a result of the increase in its production due to rapid urbanization and the problem of getting functionally adequate landfill sites for its disposal. Physical properties if sewage sludge from one of the two waste treatment plants located at the University of Ibadan were investigated. The properties evaluated were specific gravity, colour, particle size distribution and pH. The colour of the sewage sludge changed from greenish-brown when fresh to brownish-orange after incineration when the organic materials had been burnt off. The specific gravity was 1.9 while the pH was 7.32. The particle size grading of the pulverized sewage sludge was similar to that of cement, which it was meant to partially replace. The properties if fresh and hardened concrete, in which cement was partially replaced with 0, 5, 10, 15 and 20% of pulverised sewage sludge ash by weight, were determined. There was an improvement in workability with increasing sludge ash content. The best performance of sludge ash concrete was attained with 10% sludge ash content. Concrete with up to 20% replacement of cement with pulverized sewage sludge ash produced concrete with properties above grade 20 concrete

Redressing the growing concern of the education sector in Nigeria

The status of the Nigerian educational system at the moment is unenviable. It is low in quality and standard, limited in its reach and disturbing in its future. There have been some deliberate attempt/efforts by government to redress the declining fortune of the educational system. Some International donor agencies, like UNICEF, the World Bank, UNESCO, and DFID are also collaborating with government at all levels with a view to coming up with a holistic approach in addressing educational concerns. The intention of this paper is to enhance debates on how to redress past mistakes and unintended failures within the Nigerian education policies, programmes and provisions. The paper is of the view that Nigeria requires a system that will insulate education from unnecessary politicization. Education formulation and policy consideration should be for the good of all. The paper is also of the view that there is need for a holistic reorientation, re-engineering and re-branding of education, especially teacher training and recruitments, if effective quality of education is to be achieved in Nigeria. Government should also ensure that all reports, pronouncements and positions canvassed by educational accreditation, visitations and probe panels are implemented. Key Words: Education, Minimum academic standard; Politicization of education; Quality, Teacher recruitment
