What is sand cone test?

Sand cone test is detemination of silt content of sand


What is the process of calculating quantity of cement sand metal in concrete mix design?

Choose the grade of concrete & assume minimum water/cement ratio.Conduct some initial tests on the materials like cement, sand & metal(coarse aggregate).Tests like UNIT WEGHT, SPECIFIC GRAVITY,SIEVE ANALYSIS,SLUMP CONE TEST & COMPACTION FACTOR TEST. According to the obtained results do the mix design from IS CODE of IS800-10262 check for water cement ratio & calculate the quantity of cement, sand & coarse aggregate.


What is specific gravity of portland pozzolona cement?

The specific gravity of portland pozzolana cement is 3.15.The specific gravity test can be done on cement using the bottle method.In this method instead of water kerosene is used to test the specific gravity of cement.

What grade of concrete will result in a mix of 3 2 1?

Mixing concrete is a basic skill that all DIY enthusiasts should know how to do. Concrete is one of the most common and inexpensive construction materials on the planet being comprised mostly of sand, gravel and cement. Mixing concrete is similar to baking in that to achieve consistent results it is best to follow a specific recipe. There are a multitude of different concrete mixes for different applications depending on the strength, workability and application for the concrete. Mixing concrete is very much a science for professionals, but to the average backyard enthusiast, learning the basics of concrete is enough to get you started. When mixing concrete you will need to mix aggregates such as sand and gravel along with cement powder and water as a catalyst to begin the chemical process of bonding the ingredients together. Mixing concrete is a function of proportions where you will measure the volume of aggregate used to the volume of cement used. The most common concrete mix used worldwide is the 3-2-1 mix which uses three parts gravel, two parts sand and one part cement. Water is added with the idea that you should use as little water as possible to make the concrete workable for what you need it for. Concrete viscosity is measured by "slump" which refers to a specific test where the amount that a cone filed with concrete will lose its shape once the cone is removed is measured in inches or mm. A concrete with zero slump would be very rigid and dry and inclined to hold its shape, where a concrete with a slump of six inches or more would be extremely wet and not inclined to hold a shape. The 3-2-1 mix is so widely used since you can fill large areas with concrete for relatively cheap. You could potentially use only sand and cement, no gravel, to create what is called mortar. In the 3-2-1 mix the gravel serves as a filler taking up a great deal of space while retaining a relatively high overall strength. The disadvantage of the 3-2-1 mix is that the larger gravel aggregate will often float to the surface during finishing, and is unsuitable for thin or detailed concrete applications. The best overall mix for a DIY enthusiast to memorize and use is a simple 3:1 mortar mix. By using three parts sand and one part mortar you can create the strongest concrete possible as well as concrete that is easy to finish and detail with designs, templates or stamps. By not using the gravel the mortar will have a smoother overall consistency, but will ultimately occupy less volume than concrete made using gravel as well. If you are pouring very large volumes of concrete the gravel could prove to be cost effective however for most DIY projects a 3:1 mortar mix is the way to go. The sand that you need to use for a 3:1 mortar mix should be sharp sand, or masonry sand or jointing sand. Each place that you purchase sand will use a different term so it can be confusing when shopping. All that you need to remember is to avoid play sand. Play sand is sand that has been washed and sterilized (this is ok) and then tumbled to soften all the edges of the individual sand grains (this is bad). The sharp edges of the sand help to hold together the concrete mix better than the rounded edges of the tumbled sand. Ideally you would like to find sand from landscape supply stores which will sell to you by the cubic yard. With a strong trailer you can pick up as much sand as you could possibly need for next to nothing - plus the quality of the sand for making cement will be very high. The applications for a DIY enthusiast to use a 3:1 mortar mix are huge. Everything from fixing broken outdoor steps and stairs, driveways, patios, decks, ponds, waterfalls, artificial rock, statues and much more is possible with a simple mix of sand, cement and water. Start with small concrete projects to get a better feel and understanding for how to work with concrete. Since concrete is so popular world wide, and is a highly advanced science, you will never run out of interesting concrete applications to learn about or try. Combined with being the most affordable construction material on the planet and readily available everywhere - learning to mix basic concrete recipes is a fundamental DIY project. Canadian author and second generation swimming pool expert Steve Goodale has an extensive tutorial series and online following for his instructional information on artificial rock and swimming pool construction and repair.

In soil mechanics what is sand cone method -?

The Sand Cone Method is a sand replacement method for determining the field unit weight or the in-situ density of natural or compacted soil. There are three standard procedures used for determining this weight, including the Sand Cone Method, Rubber Balloon Method and the Nuclear Method. In the Sand Cone Method, as done in this lab, a hole is excavated in the area where the soil has been compacted and the dry weight of the soil can be obtained by determining the weight of the moist soil and the moisture content. The volume for the hole excavated is calculated by reintroducing the sand into the hole and then the dry unit weight of compaction is calculated by dividing the dry weight of the soil by the volume of the hole. This test method is applicable for soils without appreciable amounts of rock or coarse materials in excess of 1 1/2 in. (38 mm) in diameter. The main application of this test is the cases like embankment and pavement construction, this is basically a quality control test where a certain degree of compaction is required. This test is also used in stability analysis of embankments and slopes, for the calculation of pressure in underlying strata for settlement problems and also design of underground structures.
