Experimental study of lightweight concrete prepared from super absorbent polymers (SAPs) and glass fibers (GF)

open access: yesJournal of Asian Architecture and Building Engineering
This study investigates the effect of super absorbent polymers (SAPs) and glass fiber (GF) additions on the properties of lightweight concrete. The SAPs act as a pore-forming agent, with the addition of various GF contents (0.1–1.0% by weight of dry ...

New automatic minidisk infiltrometer: design and testing

open access: yesJournal of Hydrology and Hydromechanics, 2015
Soil hydraulic conductivity is a key parameter to predict water flow through the soil profile. We have developed an automatic minidisk infiltrometer (AMI) to enable easy measurement of unsaturated hydraulic conductivity using the tension infiltrometer ...

The Effect of Controlled Permeability Formwork with Different Curing Methods on the Durability Characteristics of Concrete [PDF]

open access: yes, 2010
Controlled Permeability Formwork (CPF) can be used to improve the strength, durability and appearance ofconcrete. This is achieved by allowing excess water and gas to escape at the surface adjacent to theformwork.
