DURABILITY OF ALKALI ACTIVATED COMPOSITES IN SULPHATE EXPOSURE

In this program durability of alkali activated slag mortars exposed to sulphuric acid was investigated. The alkali and silicate content of the activator solution was kept constant. In this program physico-mechanical properties of alkali activated slag mortars with varying alkali content was investigated. The alkali content of the activator solution was varied keeping the silicate content constant to determine various...

Toughness and ductility characteristics of recycled polyethylene micro-fibre reinforced concrete beams

The paper presents results of investigation on the influence of different volume fractions of polyethylene fibre on the toughness and ductility characteristics of normal strength concrete beams. Nine conventionally reinforced concrete beams measuring 150mm×200mm×2500mm containing 0.25%, 0.50% and 1.0% of polyethylene fibres were cast and tested under a two-point symmetrical loading system using an Avery Denison universal...

Durability of Alkali Activated Mortars Exposed to Sulphuric acid

In this program durability of alkali activated slag mortars exposed to sulphuric acid was investigated. The alkali and silicate content of the activator solution was kept constant. Durability of the alkali activated ground granulated blast furnace slag (AAGGBFS) mortars was assessed by investigating the change in weight, change in specific gravity, change in water absorption, , change in compressive strength before and...

A Comparative Study of Sustainable End-of-life Management in Automobile and Construction Industry: A Case Study of Kano City Nigeria

It was argued that it is either the construction industry is to continue to be conservative and inefficient on the premise that it is distinctive or it should open-up to learn lessons from the best practices models in the other sectors like manufacturing. This paper is a comparative study of sustainable end-of-life management practices in the automobile and the Nigerian building sector with the aim of examining the...

Investigation into the properties of self-compacting concrete with palm kernel shell ash as mineral additive

This study investigates workability and the compressive strength properties of self- compacting concrete incorporating palm kernel shell ash (PKSA) as mineral additive for partial cement replacement.. The mix design was based on the iterative method where solid constituents were adjusted while water and super plasticizer contents were fixed to produce optimum viscosity and flowability. All mixes were designed to achieve...

A literature review on natural fibers, its properties and influence of water absorption on mechanical properties of composites

Natural fibers composites are low-cost fibers with high specific properties, low density and eco-friendly. The development of advanced bio composite materials made is increasing in the world. It will be an alternative way to develop the bio-composites which can be particularly used for daily needs of common people whether it is house hold furniture, house and light weight car components and other equipment. This effort to...

A simple engineering soil surface vibration prediction method

In urban areas where the infrastructure is dense and construction of new structures is near existing and sensitive buildings, frequent vibrations caused by human activities occur. Generated waves in the soil may adversely affect surrounding buildings. These vibrations have to be predicted a priori by using currently available knowledge of the soil dynamics. In order to make a good prediction of the soil surface vibration,...

Effect of aggregates minerology on the strength of concrete: Case study of three selected quarry products in Ghana

Concrete is the most popular construction material worldwide. More than 50% of construction worldwide use concrete materials, mainly because of its versatility and economy compared to steel in relation to total height of building. The final output of the concrete material is, however, affected by factors including the rock type and its attendant physio-mechanical properties. This paper seeks to investigate the effect of...

Influence of coarse aggregate size and superplasticizer on the compressive strength and drying shrinkage of laterized concrete

This study presents the results of the influence of coarse aggregate size and superplasticizer on drying shrinkage and compressive strength of laterized concrete. The compressive strength was determined on cubes of 150 × 150 × 150 mm. A total of 3 cubes were cast for each test specimen, different sets for 7, 14, 21 and 28 days bringing the total number of cubes cast to 48. The specimens were cured and subjected to uniaxial...

Laboratory investigation of plantain peel ash as stabilizer of lateritic soil for road construction

Usually, the costs of conventional additives (portland cement, lime, etc) for stabilizing roads are all on the high side. However, plantain peels ash (PPA) is an agricultural waste obtained from plantain. The lateritic soil sample used in this research was obtained from a borrow pit, laboratory tested and classified as A-7-5(3) [AASHTO classification]. It was then stabilized with varying percentages of PPA (2, 4, 6, 8 and...

Geotechnical investigation of spoils from Amasiri sandstone quarries, Southeastern Nigeria for use as pavement materials for highway construction

An attempt was made to investigate the suitability of sandstones quarry spoils from Amasiri, Southeastern Nigeria for use as subbase in highway construction. Fifteen samples were subjected to some geotechnical analysis using British standards. From the results, the plasticity indexes are lower than the maximum value of 25% recommended for sub-grade and lower than 12% maximum for use as sub-base materials for roads and...
