Concrete mixes in 1:2:4 ratios of cement, sand and SSA; batched by weight, and a water cement ratio of 0.6 were considered. However, a control mix using normal aggregate (NA) was made in order to evaluate the variation in properties of the concretes. The study utilised SSA and NA ...
Diagonal cracks also propagated from each of the supports to the point of the application of load, indicating shear failure. The failure mode of the test specimens varied with the shear span - effective depth ratio as well as the concrete mix type. 展开 ...
There was no impact on the fluorescence wavelength due to factors such as strain conditions, water/cement ratio, and curing period. The advantage of imaging using IR fluorescence is that one can use a filter to record images at the target wavelength and know that visible features are due only...
The concrete mix ratio PKS:PKF of 50:50 for 1:1:3 and 1:2:4 has compressive strength of 12.29N/mm 2 and 10.38N/mm 2 after 28 days, which confirms light weight concrete. Thus, from the result obtained from this research, both palm kernel shell and palm kernel fiber could be used ...
This paper presents some of the practical results of this approach in terms of design limits and mix design recommendations. Design guidance is given such that a matrix of factors may be optimised, including water/binder ratio, binder type, cover depth, environment, and construction practice, in...
[12]. In a low water/binder ratio mix, there are morecement grainsand consequently less water per unit volume so that cement grains are muchcloser to each other leading to reduced porosity. According to Griffith’s theory[13], for the rupture ofbrittle materialswith internal cracks, it is ...

It was also found that of the coarse aggregates, size 20mm produced concrete with highest compressive strength in all the mixes irrespective of water/cement ratio and curing age. Concrete's compressive strength increases with increase in curing age and with richer mixes. Based on the findings of...
