Analysis Of The Effect Of Polypropylene Polymer (Crushed Plastic Waste) On Oven Dried Laterite Bricks
ABSTRACT The sandcrete blocks have been a major material for the construction of structures in Nigeria. This material have provided a means of constructing walls and partition. However, the sandcrete blocks also have the disadvantage of cost and unavailability of materials such as granite, cement and other combining aggregates.Laterite, a readily available material can be efficiently used to produce Laterite bricks which can be fired to improve it's mechanical and physical property. Th...
STUDY OF HYDRAULIC JUMP IN A RECTANGULAR FLUME BY COMPARING RECTANGULAR BLOCK WIER AND SLUICE GATE
This experiment was conducted in order to have a broader knowledge on hydraulic jump and its applications. It was performed in the hydraulic laboratory of the department of Water Resources and Environmental Engineering, Ahmadu Bello University, Zaria, using the TQH23, 2.52m flow rectangular channel and the HID hydraulic bench which provides water to the channel with the aid of the pump incorporated in the HID.Five different discharges were obtained by varying the flow. Hyd...
Inventory of University of Ibadan Road Facilities
Road inventory is the compilation of information about the state and condition of the road system. This study was carried out to collect road data and analyze selected road facilities within the University of Ibadan to serve as an inventory for future purpose. This was done to help resolve the issue of insufficient information about the road facilities within the University premises. In this project a survey of the roads was done which involved the use of photo/video log system and th...

Investigation on the mechanical properties of sagbama aggregate (flexural property)
ABSTRACTThis study investigation on the mechanical properties of Sagbama rice granite was analyzed to determine the load that would cause ultimate flexural stress on the material when used in concrete construction .This is necessary to make decision on where it is suitable for use. This study requires the production of 12 concrete beams of 100mmx100mmx500mm with sagbama rice granite as coarse and fine aggregate. Three (3) specimens were produced to be tested at 7, 14, 21 and 28days.Mix ratio ...
GEOTECHNICAL CHARACTERIZATION OF LATERITES STABILISED WITH SAWDUST ASH-LIME AS SUBGRADE MATERIAL IN ROAD CONSTRUCTION
ABSTRACT Samples of laterites classified by American Association of State Highway and Transportation Officials (AASHTO) as A-7-6 and A-7-5, collected from two different borrow pits in Ado-Ekiti were tested for the assessment of their geotechnical properties in natural and stabilized states. The research is aimed at assessing effects of sawdust ash (SDA), lime and the combination of sawdust ash and lime (SDAL) on the proper...
Assessment of the effects of lime and cement on geotechnical properties of laterites
Abstract- Two different samples of soil tested as A-7-5 and A-7-6 were stabilized respectively with lime and cement. The samples were stabilized with the additives in steps of 2% and subjected to laboratory tests such as consistency limits, compaction, California bearing ratio (CBR) and unconfined compressive strength (UCS) until it reached 10% additives by weight of dry soil sample. The Proctor energy type of compaction and soaked method of CBR was adopted for the research while the compress...

Domestic water treatment using moringa oleifera seed powder
ABSTRACTMost people living in rural communities, have no access to good domestic water for consumption. The inhabitants depends on rain water, well water and sometimes surface water for consumption. Improper treatment of water gotten from these sources, can lead to the spread of water borne diseases, because, sometimes the water gotten from these sources are turbid. Although, some inhabitants use alum to treat the water so as to make the water clear. But excessive usa...
STRENGTH ASSESSMENT OF NO-FINES CONCRETE PAVEMENT
ABSTRACTThe purpose of this project work is to assess the strength of No-fines concrete pavement. No-Fines concrete is use in low traffic volume, pathways, sidewalk and parking lots. No-fines concrete is produced by using ordinary Portland cement, coarse aggregates, and water. In this study, Two (2) batches of no-fines concrete each with two different water – cement ratio 0.36 and 0.45 and cement – coarse aggregate 1:4 and 1:6 were prepared to find the mix that generated high compressive ...
The Geotechnical Properties of Soils along Appleton/Zoo Road
ABSTRACT This project was undertaken to determine the geotechnical properties of soils along Appleton/Zoo road. A total of nine (9) samples, both disturbed and undisturbed, were collected at chainages - 0+275, 0+325 and 0+525 respectively and each drilled to a depth of 1 m and at sampling depths of 0–0.3 m, 0.3–0.6 m and 0.6–1.0 m respectively. These samples were subjected to the following laboratory tests: Particle (grain) size analysis comprising determination of percentage ...
Stabilization Potential of Openly Burnt Coconut Waste AshesonA-7-5 Soi
Soil materials are a vital element in all civil engineering designs hence the first step in any geotechnical engineering project is to identify and describe the soil condition if not suitable, disposal or stabilization of the soil should be carried out . In lieu of these, this research was carried out to study the effects of coconut waste ash (CWA) derived from open uncontrolled burning on lime stabilized A-7-5 soil for road construction. Natural soil was collected from a borrow pit location ...

Dewatering in Construction Works
Dewatering means “the separation of water from the soil,” or perhaps “taking the water out of a particular construction problem completely.” Areas that once were deemed unsuitable for construction due to a high water table are now being developed to meet the needs of an increasing population. With the decline in land availability to build or expand highway networks above ground, underground facilities, such as mass-transit lines, may represent the future of transportation. Under...
