Rational Mix Design Approach for High Strength Concrete Using Sand with very High Fineness Modulus 1Kwan Wai Hoe and 2Mahyuddin Ramli 1Department of Building Technology, School of Housing, Building and Planning 2University Sains Malaysia, Pulau Pinang, Malaysia Abstract: Problem statement: Production of concrete is always deal with inconsistency.
Problem statement: Production of concrete is always deal with inconsistency. Sources of variation like materials from different geographical basis, mix design method, fineness of aggregates and so on will attribute to different level of achievement of the concrete. Even though researcher had verified that higher fineness modulus of sand would yield better performance for the concrete, but so ...
Duff Abram, an early pioneer in concrete technology, proposed a method of using the fineness modulus (FM) for concrete mixture proportioning. His research showed that aggregates with the same FM would produce concrete with the same strength. The following, taken from "ACI Terminology," defines FM: "A factor obtained by adding the total ...
Fig. 1: Specific Surface versus Compressive Strength of Cement Fineness of cement is tested in two ways : (a) By sieving. (b) By determination of specific surface (total surface area of all the particles in one gram of cement) by air-permeability apparatus. Expressed as cm 2 /gm or m 2 /kg. Generally Blaine Air permeability apparatus is used. 2.
1.1 This test method covers determination of the fineness of hydraulic cement, using the Blaine air-permeability apparatus, in terms of the specific surface expressed as total surface area in square centimetres per gram, or square metres per kilogram, of cement. Two test methods are given: Test Method A is the Reference Test Method using the manually operated standard Blaine apparatus, .
Effects of cement fineness on cement properties. Q. How does the fineness to which the clinker is ground affect the properties of the cement? A. Increasing the fineness increases the rate of hydration of cement, which increases the rate of gain in strength and also the rate at which heat is liberated as in Type III compared with Type I cement (ASTM C150).
6. Dry the sample again to a constant weight on a hot plate or in an oven at a temperature of 230°F (110 ºC), then accurately weigh and record. 7. Separate the sample into individual sizes using the proper sieves. The sieves normally used are the standard 8 inch (200 mm) sieves.
Jun 18, 2014· Overview Blaine's air permeability apparatus consists essentially of a means of drawing a definite quantity of air through a prepared bed of cement of definite porosity. The fineness is expressed as a total surface area in square centimeters per gram. Apparatus Measuring instruments Name Range Accuracy Blaine air permeability apparatus Refer to IS:5516 Balance 3 [.]
Procedure to determine fineness of cement i) Weigh approximately 10g of cement to the nearest 0.01g and place it on the sieve. ii) Agitate the sieve by swirling, planetary and linear movements, until no more fine material passes through it.
For conventional concrete the fineness modulus of the fine aggregate should range from 2.3 to 3.1. A higher fineness modulus represents a coarser material and a lower fineness modulus represents a finer material. Knowing the fineness modulus of aggregate gives you some indication of the amount of paste needed to make concrete using the ...
1.1 This method determines the fineness modulus of concrete fine aggregate used in evaluation of natural and manufactured sands for portland cement concrete. 1.2 The values given in parentheses (if provided) are not standard and may not be exact mathematical conversions. Use each system of units separately. Combining values from
Fineness test of cement is done to determine the particle size of cement. As, the rule of thumb, the finer the cement particle the best will be the cement and on the other hand the coarser the particle it will not be that good. The fineness of cement is determined by two methods; 1. Sieving Method. 2. Air Permeability Method (Blaine Method).
Fineness modulus is the number at which the average size of particle is known when we counted from lower order sieve size to higher order sieve. So, in the calculation of coarse aggregate we need ...
The scope of tests on the properties of concrete using fineness cement consisted of the fundamental tests with fresh concrete, slump, air contents, and setting time [9–11]. The experiment was planned with the following targets; slump of 120 mm ± 25 mm, water-to-cement ratio of 0.5, and air content of 4.5% ± .

The Fineness modulus of cement is an empirical figure obtained by adding the total percentage of the sample of an aggregate retained on each of a specified series of sieves, and dividing the sum by 100. The proportion of cement of which the grain sizes are larger than the specified mesh size is thus determined. Contents:Fineness Modulus [.]

Sep 01, 2014· What is Fineness Modulus of Aggregate? Fineness modulus is an empirical factor obtained by adding the cumulative percentages of aggregate retained on each of the standard sieves ranging from 80 mm to 150 micron and dividing this sum by 100. Why to Determine Fineness Modulus? Fineness modulus is generally used to get an idea of [.]
The workability-dispersion-cohesion method is a new proposed method for the design of normal concrete mixes. The method uses special coefficients called workability-dispersion and workability-cohesion factors. These coefficients relate workability to mobility and stability of the concrete mix. The coefficients are obtained from special charts depending on mix requirements and aggregate properties.
Methods of finding fineness of cement: Fineness of cement is found by two methods A) By method of dry sieving B) By specific surface method- finding fineness of cement using Blanine's air permeability apparatus. Though method B is more accurate it is rarely used for specific purpose.Method A is quite good for field work.
Therefore, fineness modulus of aggregate = (cumulative % retained) / 100 = (275/100) = 2.75 Fineness modulus of fine aggregate is 2.75. It means the average value of aggregate is in between the 2 nd sieve and 3 rd sieve. It means the average aggregate size is in .
However, experimental evidence suggests it is inferior to the fineness modulus where aggregates for concrete are concerned. A further item is the 'D-m-s method' in which the fineness modulus and specific surface are both used for grading evaluation, to combine the advantages of the two methods.
