CHAPTER TWO - [ Total Page(s): 6 ]While inorganic retardants include; oxide of lead and zinc, phosphates, magnesium salt fluorides, soluble zinc, soluble borates etc.3. Air-entrainers: These are probably the most important group of admixtures. They improve durability of concrete; in particular, it’s resistance effect of frost and de-icing salts. The entrainment of air in the form of very small and stable bubbles can be achieved by using framing agents based on natural wood resins, animal or vegetable fat an ... Continue reading---
CHAPTER THREE - [ Total Page(s): 8 ]CHAPTER THREE3.0 PROJECT METHODOLOGY For successful accomplishment of the aims and objectives of this project the following methods are applied.i. Market survey for the most commonly used cement was carried out and it was found that elephant and dangote cement are the most commonly used in the locality due to their availability in the market all time.ii. Text books, internet and some experienced practicing engineer are consulted in order to obtain relevant and detailed ... Continue reading---
CHAPTER FIVE - [ Total Page(s): 1 ]CHAPTER FIVE5.0 CONCLUSION Based on the results of this investigation, the following conclusion is drawn; Admixtures affect properties of concrete like its slump value, density, compressive strength, etc. Admixtures generally decrease the slump value of concrete which in turns decrease the workability of the concrete, since normal concrete(0% concrete) has a slump value of between 55-60mm while concrete with admixture has slump value lesser ...
