The research encompassed particle size determination and Atterberg limits testing to classify the samples, primarily composed of lateritic soil. The results detailed the particle size distribution and indicated the soil's composition, predominantly sand with gravel and unaccounted finer silt content. The Atterberg limits testing revealed variations in plastic and liquid limits across different cement percentages. Additionally, dynamic and static compaction tests were performed, indicating Optimum Moisture Content (OMC) and Maximum Dry Density (MDD). The static compaction involved replacing proportions of bulk sand with cement for each percentage addition. The study achieved its objective of understanding soil properties for stabilization purposes, offering insights into the impact of varying cement content on soil characteristics and compaction. The abstract emphasizes the comprehensive investigation into lateritic soil properties and the influence of cement stabilization, vital for engineering applications in the Takie area of Ogbomoso.

The study employed various testing methodologies to assess soil characteristics, particle size distribution, and California Bearing Ratio (CBR) under different stabilization conditions. Chemical analysis compared Ordinary Portland Cement (OPC) and BLA, demonstrating distinct differences between the two materials. The results of particle size distribution affirmed an intermediate, moderately graded soil with low clay content primarily comprising sand and gravel. The CBR tests unveiled the considerable influence of cement and BLA percentages on the soil's bearing capacity in both unsoaked and soaked conditions. Notably, the introduction of 2% cement displayed the highest CBR value, especially when paired with 10% BLA, showing promising results for soil strength enhancement. Conversely, the impact of BLA on soil strength in soaked conditions was less pronounced. This research provides valuable insights into the use of BLA and cement stabilization in lateritic soil, contributing to the understanding of soil behavior for engineering applications.

This comprehensive study evaluated the rate of workability and slump value reduction of sawdust and steel fibres on the workability of cement composites. It revealed that sawdust has a significant influence on workability, even surpassing the effect of steel fibres. The research demonstrated that the combined inclusion of both materials led to a substantial reduction in slump values across various trials, with reductions ranging from 0% to 55%. Notably, trials with higher sawdust content and lower steel fibre content experienced the most pronounced reductions. For instance, a 10% addition of sawdust resulted in a 22% reduction in slump value. These findings provide valuable insights into the optimization of cement composite mixtures for construction applications, underscoring the intricate interplay between steel fibres and sawdust in the modification of its workability.

Urbanization accounts for the major reason which pulls migration, and the environment is the fiber and bedrock upon which Urbanization thrives. As Urbanization occurs, the environment is modified to accommodate its new population. Ideally, in modifying the environment to accommodate urbanization, care should be taken to avoid any form of exploitation, degradation, abuse, and misuse. In the Nigerian context however, urbanization has occurred rapidly through unsustainable activities and lifestyles that both deplete and pressure the environment and the lives of the very inhabitants it should so dutifully protect. This research paper analyzes how Nigeria's rapid urban growth is affecting landscape design and sustainability. It highlights the history of urbanization both globally and locally, as well as addressing the menaces and negative impact of the movement citing examples in certain Nigerian cities. It goes on to establish the role of landscape in Urban Spaces and how they play Sustainability, Health, Aesthetic, Social, Agricultural, Ecological, Economical, Acoustic and Conservational roles in impacting the urban spaces in Nigeria. It concludes by recommending strategies for ensuring success in the use of landscape as a tool for mitigating the negative effects of rapid urbanization in Nigeria.

With this move, cities, which may have begun as small compact units with just enough facilities to accommodate its pioneering dwellers begin to grow. This growth is called Urbanization, and it also occurs naturally through the increased births in the city. Believed to have begun in 4300-3100BCE in the Uruk period of ancient Mesopotamia when a certain "prosperous and efficient village attracted the attention of other less prosperous tribes who then attached themselves to the successful settlement" (Mark, 2014). Slowly but surely, this urbanization pattern has repeated itself in all nations around the globe further compounding the climate change crisis. Asia, which has 30% of the global land mass, and is home to nearly half the world's population, has urbanization traced to rural-urban migration inspired by administrative, commercial, and maritime cities which now have gained political significance. When analyzed individually, East and NorthEast Asia is rapidly urbanizing. SouthEast Asia features relatively high urbanization rates, South and SouthWest Asia are one of the least urbanized with high Urbanization rates centered in the oil-rich central Asian countries and very low in the "non-fossil-fuel-producing and less diversified economies, such as Kyrgyzstan and Tajikistan." China, believed to have half of its population living in cities is hailed for its successful urbanization practice which was achieved by either limiting rural-urban migration or directing this movement away from the big cities towards growing or medium-sized ones, drastically limiting the number of slums. This urbanization has been experienced in every country, at different rates with an estimate showing that more than 50% of the world's population presently live in urban areas. Urbanization in Nigeria The urbanization in Nigeria is both rapid and continuing. 5 out of the 30 largest urbanized cities in Africa are in Nigeria, and her urban population is recorded to be growing at an alarming rate of 4.3 percent per annum, with an estimate that in 2037, her urban population would have doubled(URBANET, 2018). The main cause of urbanization in Nigeria can be summarized by the rural push and urban pull effect (Jedwab, Christiaensen, and Gindelsky, 2014). The rural-push effect refers to the unpleasant situations that make living in rural areas undesirable for Nigerians, and these include insecurity, rural poverty, lack of amenities and infrastructure, etc. The

In response to the escalating urban issues, a collaborative effort has emerged among local government bodies, businesses, non-profit organizations, and the residents themselves, all united by the vision of creating smarter cities. The smart city concept centers on the harmonious integration and synergy of human capital, social assets, and Information and Communication Technology (ICT) infrastructure. Its objective is to promote sustainable economic development and make better the overall quality of life. This paper therefore focused to define smart cities and ways of improving smartness of city. It also adopted review of literatures to explore the elements and components of smart city in order to arrive at a comprehensive defi...

However, the use of stabilised bricks has not been fully incorporated into high rise building construction due to its overall weight which is one of the major considerations for multi-story buildings. This research on light weight bricks was carried out to ascertain its suitability for various applications in high rise building and engineering constructions. The production was done using different percentages of Ordinary Portland Cement (OPC) and Saw Dust (SD) to establish the percentage required for light weight construction while maintaining the optimum compressive strength required for performance in building construction comparable with that of a sandcrete block to confirm its suitability for use in...

The Impact test was carried out according to ASTM [1] and ASTM [2] using a manually operated impact-tester machine. Mat Lab R2013a model was used to analyze the results of the impact strength. The average impact strength obtained were 98.776, 91.904, 85.463, 79.021 and 69.144 kJ/m2 for 0, 5, 10, 15 and 20% Ash contents respectively. The impact strength remained constant at 118.530 kJ/m2 with the addition of CCA at 0, 5, 10 and 15% but decreased at 20% cement replacement at the first trial. Mathematical models were developed for predicting impact strength of KF and CCA roofing tiles using Mat Lab R2013a model. The results show that corn cob ash and kenaf fiber can be used for sustainable housing development.
