| Abstract | ||
| It is generally accepted that only chemical grouts or solutions are available to penetrate and fill narrow joints or soils with very small pore size. Over the last 30 years a few hundred different compounds have been used for this purpose. Such materials show a wide spectrum of properties. Clayey grouts are among the compounds that are commonly used in chemical grouting because of their high strength and durability against mechanical or physical erosion. In this research work, a new filler of clayey grout is introduced consist of clay additive by two dispersing agent (sodium phosphate) and a passive material necessary for colouring the grout so it can be distinguish from the surrounding soil). In many samples, the filler has been injected with soil which required to improve, and many factors take into consideration. Results of lab tests which are employed here indicated that grout efficiency is raised with increasing number of holes, penetration depth, and it is affected clearly by variety in pattern of injection holes. | ||
