The aim of the designer should always be to get concrete mixtures of optimum strength at minimum cement content and acceptable workability ACI Mix Design ACI Mix Design ACI Mix Design Air-Entrained Concrete One of the greatest advances in concrete technology was the development of air-entrained concrete in the late 1930s
Text from page-2 Vtusolutionin ADVANCED CONCRETE TECHNOLOGY HOW IS IT MADE? Limestone for calcium and Clay or shale for Silica/Alumina is used as raw materials The manufacturing process of Portland cement clinker consist essentially of grinding the raw materials, mixing them in appropriate proportion, burning the io n in raw material in a kiln at a temperature of 1400-1500 oC ,
Conclusion After the experiment, our group was able to determine the fineness of the cement by sieve method Based on our results, we have observed that sieving process should be done properly and carefully In our data, the average fineness of the fineness of the cement is 9762% which means it passed the standard because it is clearly not less than 78%
Concrete Mix Design -Definition Concrete mix design is defined as the appropriate selection and proportioning of constituents to produce a concrete with pre-defined characteristics in the fresh and hardened stat In general, concrete mixes are designed in order to achieve a defined workability, strength and durability
Checking of materials is an essential part of civil engineering as the life of structure is dependent on the quality of material usedFollowing are the tests to be conducted to judge the quality of cement 1 Fineness 2 Soundness 3 Consistency 4 Initial And Final Setting Time Of Cement

Feb 14, 2013· PowerPoint Presentation: 9 Density and Specific Gravity • Density is the mass of a unit volume of the solids or particles, excluding air between particl The particle density of Portland cement ranges from 310 to 325 Mg/m3, averaging 315 Mg/ m3 • It is used in concrete ,
from construction or demolition waste is recommended for use in new concrete construction • The characteristic of recycled aggregates could be different by its parent concrete because the parent concrete was designed for its purposes such as permeable, durable and high strength concrete • Recycling of concrete is a relatively simple process
1- Water/cement (w/c) ratio - The setting time of cement increase with the increase of w/c ratio 2-Temperature and relative humidity -The setting time of cement decreases with a rise in temperature and decrease of relative humidity 3- Fineness of cement - The setting time of cement decreases with a rise in fineness of cement

Concrete Mix Design Lecture No 18 Concrete Mix Design One of the ultimate aims of studying the various properties of the materials of concrete, plastic concrete and hardened concrete, is to enable a concrete technologist to design a concrete mix for a particular strength and durability , Fineness modulus of selected FA
Fineness of cement Grinding is the last step in processing Measures of fineness Specific surface Particle size distribution Blaine’s fineness Measure of air permeability Typical surface areas ~ 350 m2 / kg (Normal cements) ~ 500 m2 / kg (High early strength cements)
The size of the particles of the cement is its finenessThe required fineness of good cement is achieved through grinding the clinker in the last step of cement production processAs hydration rate of cement is directly related to the cement particle size, fineness of cement is very important
