the properties of 11 cement-modified subgrades after 45 years of service showed that the improvements in soil properties (PI, shrinkage limit, and gradations) were permanent. Plasticity Index and Other Index Properties. The plasticity index (PI)3 is a measure of a soil's cohesive properties and is indicative of the amount and nature of clay ...
At higher cement contents, the end product is termed soil-cement. Higher cement contents will unavoidably induce higher incidences of shrinkage cracking caused by moisture/temperature changes. For soils to be stabilized with cement, proper mixing requires that the soil have a PI of less than 20 and a minimum of 45% passing the No. 40 …
Introduction. Soil texture refers to the proportions of sand (2.0 – 0.05 mm in diameter), silt (0.05 – 0.002 mm), and clay (less than 0.002 mm). The relative proportions determine the textural class. Soil texture influences nearly every aspect of soil use and management. Many of the physical and chemical properties of the soil depend on how ...
agglomerates. Wait 2 min. Stir the resulting powder gently using a clean dry rod in order to distribute the fines throughout the cement. 2. Fit the tray under the sieve, weigh approximately 10 g of cement to the nearest 0.01 g and place it on the sieve, being careful to avoid loss. Disperse any agglomerates. Fit the lid over the sieve.
Arrange the sieve set from top to bottom as follows 4.75 mm, 2.36 mm, 1.18 mm, 600 micron, 300 micron, 150 micron, 75 micron and Pan. After weighing the sample, transfer the sample to 4.75 mm sieve and cover it with lid. Place the assembly of sieve set on mechanical sieve shaker and sieve it for five to ten minutes.
The results of dry sieving methods are called "dry aggregates". Wet sieving is carried out in two ways: without ( le Bissonnais, 1996l ; Marquez et al., 2004 ) or after the pre-capillary water saturation ( Kemper and Chepil, 1965 ; Nimmo and Perkins, 2002 ) of an air-dried sample, resulting in " water-stable aggregates ".
Therefore, by minimizing the amount of cement, the cost of concrete can be reduced. Sieve Analysis-- determines the grading of an aggregate. Coarse aggregate is that retained on the #4 sieve and fine aggregate is that passing a #4 sieve. In a sieve analysis a series of sieve are used with smaller and smaller openings.

The pavement structure of a concrete pavement typically consists of a concrete sur-face and subbase(s) placed upon a prepared subgrade (a "base" is part of an asphalt pavement struc ture, while a subbase is an optional element of a concrete pavement structure). 1 Chapter 1.

The air jet sieve is a sieving machine for single sieving, i.e. for each sieving process only one sieve is used. The sieve itself is not moved during the process. The material on the sieve is moved by a rotating jet of air: A vacuum cleaner which is connected to the sieving machine generates a vacuum inside the sieving chamber
