One solution to the high cost and scarcity of building materials is use alternative sustainable materials. The study presented herein developed an eco-friendly masonry grout using volumes palm oil clinker powder replace cement coarse aggregate. Several batches grouts with different amounts these were made determine technical viability grout. Scanning Electronic Microscope (SEM), X-Rays Diffract...

Abstract The development and construction of offshore wind farms requires the correct estimation friction that can be mobilised at rock/grout interface. In conventional studies, shear behaviour a joint is usually investigated with laboratory tests under constant normal load/stress (CNL), however, in engineering practice, direct testing stiffness (CNS) has been proved to more realistic assessmen...

A cable-stayed bridge recently constructed by the Ohio Department of Transportation incorporates measures put forth by a Federal Highway Administration study to mitigate stay motion. In following recent trends, the stays at this bridge are built without the use of grout for the purposes of inspection and, if necessary, replacement. Several experiments were performed to determine the viability o...

The longevity of grouting has a significant effect on the safe and sustainable operation of many engineering projects. A 500-day experiment was carried out to study the long-term mechanical behavior of nano silica sol grouting. The nano silica sol was activated with different proportions of a NaCl catalyst and cured under fluctuating temperature and humidity conditions. The mechanical parameter...

Passive site remediation is a new concept proposed for non-disruptive mitigation of liquefaction risk at developed sites susceptible to liquefaction. It is based on the concept of slow injection of stabilizing materials at the edge of a site and delivery of the stabilizer to the target location using the natural groundwater flow. Stabilizer candidates need to have long controllable gel times an...
