Sandcrete blocks produced commercially in Akure have failed to meet the minimum requirement of Nigerian Industrial Standard (NIS 2000; 87: 2000) 2.5N/mm2 to 3.45N/mm2. Researchers have attributed this to soil, mix ratio, curing, and control. The purpose of the study is to use cassava waste water as an admixture to improve the quality and the compressive strength of Sandcrete blocks produced in Akure. A total of 60 sandcrete blocks size 450mm X 150mm X 225mm were produced using an admixture of 5%, 10%, 15% and 20% of Cassava waste water with 0% control, and cured for 7, 14, 21, and 28 days. The tests performed include: sieve analysis, Moisture content, Specific Gravity, Water absorption and Compressive Strength. All tests were performed to ascertain if cassava produced sandcrete blocks conform with (NIS 87: 2000, NIS: 2000) recommendations. The results obtained indicate that 20% admixture satisfies NIS requirements (3.30 N/mm2).

Electric power is a scarce commodity in Nigeria as in most developing countries like India. Intermittent power outages are witnessed in various cities and villages. Electricity is the form of energy which is most widely used in nature. Electric power obtained from the conversion of other sources of energy, like coal, natural gas, oil, nuclear power and other natural sources are called primary sources. Electricity generation was first developed in 1800's using Faraday's dynamo generator. After almost 2 centuries later, the same basic principles are still being used to generate electricity, but on a much larger scale. The primary energy resources are the conventional types and are in limited quantity because they are not renewable, and on the other hand they create pollution to the atmosphere. A revolutionary method of power generation through speed breaker power generators is proposed as an innovative and useful concept. On speed breakers, tremendous amount of energy is being wasted by vehicles, and several models were introduced to utilize this energy through speed breakers. This paper attempts to show different methods of renewable energy generation through speed breaker.
