What Is The Fineness Modulus Of Good Quality Cement

The fineness modulus is obtained by adding the percentage of weight of the material retained on the following sieve and divided by 100. The coarser the aggregates, the higher the fineness modulus. Sieve is adopted for: All aggregates : 80 mm, 40 mm, 20 mm, 10 mm, and Nos. 480, 240, 120, 60, 30 and 15.

To check the quality of cement some of the following tests are performed on cement, 1. Fineness Test of Cement 2. Consistency Test of Cement 3. Setting Time Test of Cement 4. Soundness Test of Cement 5. The Heat of Hydration Test 6. Specific Gravity Test of Cement 7.Tensile Strength Test 8. Chemical Composition Test

Presence of free CaO affects the quality of clinker and produce unsound cement. Clinker burning hard with high fuel consumption. Free lime content is low and the high the early strength of the cement. Difficult to combine with other oxide (hard to burn)….. a

Good-quality aggregate must be clean, hard, strong, have durable particles, and be free of absorbed harmful chemicals, coatings of clay, or other contaminates that can affect hydration of cement or reduce the paste-aggregate bond.,The fineness modulus (FM) is an index of the fineness of an aggregate.,The fundamental relationship between,

Fineness modules. Fineness modulus is an empirical factor obtained by the sum of the total percentages of a sample of the aggregate retained on each of the specified series of sieves per 100. i.e. Fineness modulus (F.M.) = Sum of Cummulated percentage retained / 100 = ⅀R/ 100. You’ll also Like:

Sieve Analysis Test Procedure. The following is the test procedure for sieve analysis test of sand, Take the required amount of aggregate sample (for a sand (fine aggregate) minimum of 0.5kg sample is required.; Arrange the required no of sieves as per the contract or job requirement in a descending manner.

6) Increase the amount of fine aggregate if sand is coarser (fineness modulus of 2.5 to 2.8 best suited) in mix and reduce aggregate proportionally. Proper measures should be taken during preparation of mix and method of mixing to reduce bleeding as it might result in weak structure and a delay in construction cycle.

Jul 03, 2019· The Portland cement is used to make mortar. Ordinary Portland cement is most suitable for common construction purposes. For making composite mortars, Lime is also used. Also Read: Manufacturing Process of Ordinary Portland Cement (OPC) Sand must be of good quality and it should be free of impurities like clay, dust, oxide of irons etc.

Ground granulated blast furnace slag (GGBS) was employed as the main component of an alternative binder. Ground agricultural gypsum and construction-grade hydrated lime were used as activators in the proportions of 0.88:0.10:0.02 (GGBS:gypsum:lime) by mass as previously discussed (Oliveira et al., 1999).Sisal (Agave sisalana) field by-product was selected from a

Bamboo fiber-reinforced maleated PP composites having bamboo fibers of different sizes (<500 µm, 500–850 µm, 850 µm to 1 mm, and <2 mm) show different mechanical properties [10].The tensile strength and modulus of bamboo-reinforced MAPP increase with increasing content up to 65 wt.% (Fig. 6.3A and B).A tensile modulus of 3.4 GPa is obtained for 50 wt.% filled PP

The Density of Sand utility returns sand density based on sand conditions (wet/dry in bulk / packaged).. The density of the sand is affected if the sand is compacted (bulged) or loose and if it is wet or dry.When packed, the grains of sand are forced to form a narrower formation, and more matter is in the volume.. Natural sand i.e. locally available River sand having a bulk density of

This specification defines the requirements for grading and quality of fine and coarse aggregate for use in concrete.,crushed gravel, crushed stone, air-cooled blast furnace slag, or crushed hydraulic-cement concrete, or a combination thereof. The sampling and test methods shall be done with grading and fineness modulus test, organic,

May 17, 2017· Design mix concrete is adopted for high rise constructions. In this type of mix, the mix ratios are decided by an Engineer after analysing the properties of individual ingredients of concrete. Like, cement is tested for Fineness modulus and Specific gravity of cement in the lab while deciding the Design mix ratio. There is No Pre-fixed ratio,

Nov 01, 2017· Out of the total production, Ordinary Portland Cement accounts for about 80-90 percent. Fineness of cement = 8% Standard consistency of cement = 31% Initial setting time of cement = 36 min Specific gravity of cement = 3.46 Water: - Water is an important ingredient of concrete as it actually participates in the chemical reaction with cement.

Definition of Concrete Admixtures As per BIS (IS – 9103: 1999) Page No.1, Concrete Admixture is defined as a material other than water, aggregates and hydraulic cement and additives like Pozzolana or slag and fiber reinforcement, used as on ingredient of concrete or mortar and added to the batch immediately before or during its mixing to modify one or more of the properties of

Dec 24, 2021· The compressive strengths of fly ash-based alkali-activated materials (AAM), produced using various activators of only sodium hydroxide, were measured. Fly ash-based AAM specimens, produced by mixing different kinds of fly ash and ground granulated blast-furnace slag (GGBFs) with an activator containing only sodium hydroxide, were cured at ambient
