What is the compressive strength of cement mortar?
Compressive strength measures the largest compression force the material can withstand before it loses its shape or fails.
What is the difference between particular specification and general specification?
General Specifications•General specification are written•General Specification may include:General site requirement- Health and safety- Measures against environmental pollution- Security measuresParticular Specification•It contains particular specification.•Example :- Strength and other properties of steel- Strength of concrete- Specification of bricks- Specification of electrical itemsEtc.
What is concrete mixing ratio for c35?
The mixes of grades M5 M10, M15, M20 and M25 correspond approximately to the mix proportions (1:4:8), (1:3:6), (1:2:4), (1:1.5:3) and (1:1:2) respectively.
What is the Effect of heating on concrete structure?
All depends on How Much heat your talking about. General rule: if it is more than a concrete will experience from the sun, special concretes and additives should be employed. There are specialized products such as Fire Brick for use in a fireplace. Any mortar, grout or cementitious products used in a fireplace should also be able to stand excess or out of the ordinary heat temperatures. Common problem to a Type 1 concrete that has been exposed to fire is it becomes what is called "Friable". Lost strength! Heat a normal concrete fast enough and it will explode when the moisture inside expands!
What Factors Would Influence the Textile Tensile Strength?
The tensile strength of textile can be divided into three types: as for the woven fabric, one is tensile strength, most of fabric can reach this demand, if not, the development of this fabric is unsuccessful, can not be used to make clothing. The second is tear strength, tear the sample a hole first, then use the strength tester to tear the sample and test its sustainable strength, this is a key index and has much more substance. As for the knitted fabric, the index to check the fabric strength is bursting strength. The most relevant to the knitted fabric bursting strength are the yarn strength and fabric weight, if the fabric yarn strength is poor and the fabric weight is light, there will cause problems. The yarn fineness: as for the same material, the thicker the yarn, the better strength, so this fabric strength is higher. The yarn twist: in general, the yarn strength increase with twist, after reaching certain extent, the yarn strength decrease with twist, but it won't happen in general. The fabric density: generally speaking, the higher the fabric density, the more yarn dosage per unit area, so that the fabric strength is bigger. By YULONG FR tex
Why iron metal is used in building construction?
It deals with the tension and compression of the concrete. Concrete is a really great material when in comes to compression. It has a high strength in compression but little in the way of tension. You can test this for your self. Get a small unreinforced piece of concrete and pull it apart it ( put it in tension) and it breaks fairy easily. Now, try pushing together (put it in compression) and it doesn't break anywhere near as easily, if you can break it at all. Steel is the opposite. It has more strength in tension than in compression. Putting steel bars in concrete allows you to have good strength in compression and in tension. In an easy way to understand it and get the general idea, when the reinforced concrete is under tension, the steel bars take over, and when the reinforced concrete is under compression, the concrete takes over.
What general strength of concrete for non-suspended floors?

What is concrete's setting time?
Dependant on if you have additives with the concrete and how much water is in the mix. In general concrete will achieve 80 - 90 percent strength within in 24 hours
What is the compressive strength of cement mortar?
Compressive strength measures the largest compression force the material can withstand before it loses its shape or fails.
What is concrete shuttering?
A wooded frame is made into a shape, for example a stair case, and then the concrete is poured into the frame. After the concrete has set, the wood/shuttering is removed, leaving a solid concrete shape. Steel bars are added into the concrete as it sets to give the shape more strength. Vague description but that the general idea of it, hope it helped.

What is the Test Procedure to Determine Compressive strength of Hollow Blocks?
Testing the compressive strength of hollow blocks typically follows a standard procedure to ensure accurate and reliable results. Here's a general outline of the test procedure: **Sample Preparation:** Select representative samples of hollow blocks from the production batch. Ensure the samples are free from defects and have been cured appropriately. **Conditioning:** If the blocks are not already at room temperature, allow them to acclimate to the testing environment. **Equipment Setup:** Set up the compression testing machine according to standards or specifications. Ensure the machine is calibrated and in good working condition. **Sample Identification:** Mark each sample with a unique identifier for accurate tracking of results. **Moisture Content Check (if applicable):** Determine and record the moisture content of the samples, especially if it can affect the compressive strength. **Testing Procedure:** Place the hollow block specimen on the compression testing machine. Align the specimen so that the load is applied evenly on the blocks. Gradually apply a compressive load at a uniform rate until failure occurs. Record the maximum load at failure and note any signs of distress in the specimen. **Calculation of Compressive Strength:** Calculate the compressive strength using the formula: Compressive Strength = Maximum Load / Cross-sectional Area of the Block. **Reporting:** Document all relevant information, including sample identification, moisture content, and compressive strength values. Prepare a test report with details of the testing procedure, equipment used, and results obtained. **Quality Control:** Compare the results with specified standards or requirements to ensure the hollow blocks meet the desired compressive strength. **Data Analysis:** Analyze the data for any trends, variations, or anomalies that may indicate issues with the production process. **Documentation and Archiving:** Keep a record of the test results and associated documentation for future reference or quality control purposes. It's crucial to follow specific standards or guidelines relevant to the type of hollow blocks being tested, as procedures may vary based on factors such as block dimensions, material composition, and testing conditions. Always adhere to industry standards or applicable building codes for accurate and meaningful results.
