CLAY (CL) or SANDY SILT (ML) 3 2 SOIL PROPERTIES and STRENGTH Characteristics or properties that help predict the effect of a soil on a shoring system include the particle distribution ( gravel sand fines (silt & clay)) particle angularity apparent density or consistency (strength) moisture and unit weight
The clay component of loess (along with calcium carbonate in certain deposits) has been attributed to the cohesion that allows loess to stand vertical However upon wetting the loess can collapse resulting in excessive settlements
Clay is defined as a natural earthy fine-grained material largely of a group of crystallinehydrous silicate minerals known as clay minerals Clay minerals are composed mainly of silicaalumina and water but they may also contain appreciable quantities of iron alkalies and alkalineearths
Are brick & clay tiles good for structural applications?
While brick and structural clay tile are both visually appealing and durable, they are also well-suited for many structural applications. This is primarily due to their variety of sizes and very high compressive strength.
Which material properties affect dimensional stability of clay and shale unit masonry?
Material properties which affect dimensional stability of clay and shale unit masonry are moisture expansion, creep and thermal movements. Effects of these phenomenon may be evaluated by the coefficients provided in the MSJC Code, which are listed in Table 8.
How is compressive strength of brick & structural clay tile determined?
Compressive strength of brick and structural clay tile is determined in accordance with ASTM C 67 Method of Sampling and Testing Brick and Structural Clay Tile. 1Extruded only. 2Made from other materials or a combination of materials.3Based on gross area. Unit Texture and Absorption.
