The Compressive Strength of Light Weight Concrete

open access: yesInternational Journal of Engineering Sciences, 2020
The compressive strength of lightweight concrete using palm kernel shell (pks) and periwinkle shell (pws) is reported. The strength as a function of aggregates ,age, and density were investigated. The strengths were measured at interval of 7-day for 28 days.

On the Light-Weight Concrete Used Artifiial Light-Weight Aggregate

open access: yesjournal of the Japan Society for Testing Materials, 1962
Recently, with the tendency to lighten structures coming out, some artificial light-weight aggregates having excellent qualities suitable for high strength structural use have come to be produced for trial.We tested these artificial light-weight aggregates and light-weight concrete using these aggregates, and further, checked up the effects of these ...

Iterative structure of finite loop integrals [PDF]

open access: yes, 2014
In this paper we develop further and refine the method of differential equations for computing Feynman integrals. In particular, we show that an additional iterative structure emerges for finite loop integrals.
