A grain of rice among sand and earth
2021The purpose of this culminating project was to expand on the current literature on the topic of ethnoracial labels and unconscious bias, to provide another perspective to the ongoing conversation on systemic racism, and to create a call to action for present and future clinicians, supervisors, and educators to make changes that better reflect the ...

Construction and Building Materials, 2017
Abstract This study investigates the compressive strength of ordinary Portland cement mortar prisms with rice husk ash (RHA). Pit sand–cement, and sea sand-cement mortar prisms were separately prepared using cement-sand mix ratio 1:3, and RHA composition of 0–44.44%. The optimum strength of the pit sand-cement mortar prisms after 1, 2, 7, and 28 days

Wild Rice Lakes in Comparison to Mapped Surficial Sands in Minnesota
Wetland Science & Practice, 2023Several recent studies have considered the distribution of wild rice (Zizania palustris) compared to a variety of physical and watershed parameters. However, the distribution of wild rice has not been systematically compared to the surficial geology. In this study, a relatively comprehensive list of identified wild rice lakes in Minnesota was compared ...

Rice husk ash-carbide lime as an alternative binder for waste foundry sand stabilization
Environmental Science and Pollution Research, 2023Rice husk ash (RHA) is an excellent pozzolana and associated with hydrated lime (HL), it becomes an alternative binder to Portland cement in soil stabilization. In the context of waste valorization, waste foundry sand (WFS) and carbide lime (CL) have been investigated in civil construction and environmental geotechnical applications.

Improvement of geotechnical properties of residual sand with rice husk ash
International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1990This paper presents the results of a series of laboratory tests carried out on residual sand from Ile-Ife (Nigeria) with various percentages of rice husk ash. It has been found that rice husk ash can potentially improve the various geotechnical properties such as unconfined compressive strength, California bearing ratio, cohesion and shear strength of ...

Properties of clay-sand-rice husk ash mixed bricks
International Journal of Cement Composites and Lightweight Concrete, 1987Abstract Bricks were made from clay-sand mixes with different percentages of rice husk ash and burnt in a furnace for different firing times. The firing durations at 1000°C were 2 hours, 4 hours and 6 hours. The effects of rice husk ash contents on workable mixing water content, Atterberg limits, linear shrinkage, density, compressive strength and ...
