Abstract: A weakly cemented sand and gravel has been partly or entirely used in the construction of earth structures such as dams and retaining walls. Such cemented soils that are usually highly permeable can undergo repetitive ...

Abstract: Many regions of the world have witnessed repeated earthquakes that have caused repeated liquefaction of soil. Therefore, the effect of repeated earthquakes on the dynamic behavior of soil is an important aspect that must ...

Abstract: Recently, a new soil improvement method to use a microbially induced calcium carbonate precipitation (MICP) process to generate biocementation in sand has been developed. In this method, the properties of biocemented soil ...

Abstract: A plant (jack bean) extract can function as a urease catalyst, similar to those of certain microorganisms such as

Abstract: An alkaline-activated, ground-granulated blast furnace slag (BFS) was used as a binder for mortar prepared using river sand. Sixteen mortar mixes with four different BFS:sand ratios (4%, 8%, 12%, and 16% dry weight) were ...

Abstract: Chemically induced calcium carbonate precipitation (CCP) using calcium hydroxide (CH) and carbon dioxide (CO2) was employed to clean sand for improving its strength. Joomunjin sand was mixed with 2% CH and 10% water, and ...
