The practical will be done within 30° C temperature. Fill the bottle with kerosene up to the top and weigh the flask (W4) 5-Calculation: -For calculation procedure ,please see figure No. Ordinary Portland Cement (OPC) Le-Chatelier Flask of 250 ml or Specific Gravity Bottle / Pycnometer of 100 ml Weighing Balance with 0.1g accuracy Kerosene (. Weigh the flask with cement and kerosene (W3) 4-Empty the flask. Mix well to remove the air bubbles in it. Weigh the empty flask(W1) 2-Fill the cement on the bottle up to half of the flask (about 50gm) and weigh with its stopper (W2) 3-Add Kerosene to the cement up to the top of the bottle. PORTLAND CEMENT SPECIFIC GRAVITY LAB FREEObject: To find specific gravity of cement value Required Materials & Apparatus: 1-Ordinary Portland Cement 2-Kerosene 3-Le-Chatelier Flask capacity of 250 ml or Specific Gravity Bottle / Pycnometer (100 ml) 4-Weighing balance with 0.1 gm accurate """""""""""""""""""""""""""" Test Procedure: 1-The Flask should be free from the liquid that means it should be fully dry. But in the case of cement water is not used because. For gases, the air is taken as standard at 25C. Mostly, the standard substance is taken water at 4 C. This is an experiment conducted at the site level. The specific gravity of any substance may be defined as the ratio of its specific weight of given volume to that of a standard substance of the same volume at a standard temperature. PORTLAND CEMENT SPECIFIC GRAVITY LAB HOW TOSlump test is conducted to check its workability.Engineering Infinity - How to calculate specific gravity of cement? (((JOB INTERVIEW QUESTION))) """"""""""""""Question 11 """"""""""""""""" Using Le Chatelier Flask method, we can determine this value. GGBS replacement adopted was 0% to 25% in steps of 5%. PORTLAND CEMENT SPECIFIC GRAVITY LAB CODEThe mixes were designed using IS Code method. Concrete grades of M25 have been taken for the work. Clarification: The specific gravity of cement is 3.15, it is not like the density which is 1440 kg/m3 because here kerosene is used for density test and in 1. This paper presents the workability study of concrete with GGBS as a replacement material for cement without the addition of Super plasticizer. With this view we have made an attempt is to replace cement by a mineral admixture, (i.e.), ground granulated blast furnace slag (GGBS) in concrete mixes to overcome these problems. A concrete using cement alone as a binder requires high paste volume, which often leads to excessive shrinkage and large evolution of heat of hydration, besides increased cost. Sometimes certain additives are added to it to improve or alter some properties. With increase in demand of concrete, more and more new methods and new materials are being developed for production of concrete. So there is a need of alternative building material like geopolymer concrete to bring development economically, socially, environmentally. Portland cement, low heat Portland cement, Portland blast furnace cement and high alumina cements. PORTLAND CEMENT SPECIFIC GRAVITY LAB SERIESIn recent year man is facing a series of interrelated problems like increasing population, rapidly degrading environment, depleting natural resources and high rate of demand for construction materials. Used for finding specific gravity of hydraulic cement. The aggressiveness of hydrochloric acid on concrete was very pronounced yet, the mixes containing Fire Clay performed better than control mix against acid attack. The comparative compressive strength analysis indicated that during entire testing process, the mix containing 10% Fire clay showed higher strength than the control mix. for 25 laboratory cements of varying chemical composition in a special rotary kiln. The scanning electron micrographs indicated that the Mix contacting fire clay had a more compacted structure. At the plant of the Southwestern Portland Cement Co. The effect of Fire Clay in concrete was analyzed by its Mechanical properties and Micro structural behavior under scanning electron microscopy (SEM) and X-ray diffraction (XRD) when exposed to diluted HCL solution. It will reduce energy consumption and greenhouse gases produced during the manufacturing process of cement. Test results substantiate the feasibility to develop low cost concrete using Fire clay. A 10% addition of Fire clay was found as optimum dosage both for short and longer curing periods. The main variable is the proportion of Fire clay (10%, 20%, 30%, 40%, and 50% by weight of cement) in replacement mode while the amount of cementitious material, water to cementitious material ratio, fine and coarse aggregate content were kept constant. DENSITY OF PORTLAND CEMENT CONCRETE LAB DATA SHEET T65. This research is aimed at evaluating the fire clay, deposited at Coordinates: 32☄0′29″N 71☁6′52″E in the Isakhel (District Mianwali) as partial replacement of cement. This protocol covers the determination of the specific gravity, density, percent absorption and.

There are a few exceptions as each position group has different rules, but those are the basics. THE GRADING SCALEĮach player is given a grade of -2 to +2 in 0.5 increments on a given play with 0 generally being the average or “expected” grade. This style has worked well in unlocking undervalued gems through the years, while also not being swayed by player hype if it is undeserved. Preconceived level of ability has no impact on the grading system. We also work to eliminate bias by not caring about the level of player who is being graded, so whether it’s the best tackle in the league missing a block or one of the worst, the same grade is given. Taking every play into consideration allows for a larger sample size of data to tell the proper story rather than just a highlight reel of plays that we tend to remember, for better or worse. The benefits of this style of grading are numerous. The grading system was founded on the principle of grading “production” rather than traits or measurables, but perhaps a better way to describe it is a player’s “contribution to production” on a given play.ĭid the quarterback make a great throw, but it was dropped? The quarterback contributed to positive production and will receive a positive grade for that effort, even though the receiver let him down, earning a negative grade along the way. We believe that #EveryPla圜ounts and that attention to detail provides insights and data that cannot be found anywhere else. The PFF grading system evaluates every player on every play during a football game. PFF grades have become synonymous with player performance in both the NFL and college football over the last 10-plus years, but what goes into creating those player grades?
