Department of civil technology written by. I have completed the version 3 0 of mix design spreadsheet for labs.
The concrete hub app now provides an easy fast and free way to perform a preliminary mix design.
Concrete mix design report sample. Item numbers listed below correspond to the numbers in figure a 5 694 711. Concrete mix design is the process of finding right proportions of cement sand and aggregates for concrete to achieve target strength in structures. Ahmed zakaria 20 making blend of aggregate 3 4 3 8.
The dry rodded bulk density of c a. In concrete design an engineer should make at least 5 blend. Volume of water mass of water specific gravity of water x 1 1000 197 1 x 1 1000 0 197 m3.
Version 3 0 of mix design spreadsheet. We would like to show you a description here but the site won t allow us. Is 1600 kg m3 and.
Concrete hub s concrete mix design tool. In the report the value to two different mix are used differing in their water cement ratio. Volume of concrete 1 m3.
Any items left blank may delay receiving a mix design. To make blend make the ratio of 3 4 3 8 aggregate by dividing them into 100. The concrete hub app however solves these challenges associated with creating a unique concrete mix.
This sheet can be used to create the report. Are 2 65 and 2 7 respectively. In this spreadsheet i have added another sheet report1.
Instructions for completing the concrete mix design request form 2416 complete all items on the mix design request. The mix calculations per unit volume of concrete shall be as follows. In this report we will take ratio s 3 4.
Volume of cement mass of cement specific gravity of cement x 1 100 394 3 15 x 1 1000 0 125 m3. All concrete mixes possess unique properties the design process can be time consuming and challenging. See figure b 5 694 711 for a completed example.
Project number list the low project number. The specified design strength of concrete is 30 mpa at 28 days measured on standard cylinders. The specific gravity of fa and c a.
Estimation of concrete mix calculations. For example take aggregate 3 4 40 aggregate 3 8 60 which equals to 100 on adding ratio s similarly calculate 3 4 60 3 8 40 unless your results match the specification table try five different ratios. Performance based concrete pavement mix design system the final product of this track will be a practical yet innovative concrete mix design procedure with new equipment consensus target values common laboratory procedures and full integration with both structural design and field quality control a lab of the future.
Data to be collected design a concrete mix for construction of an elevated water tank.

Concrete mix design calculation of m20 m25 m30 grade of concrete with example.
Calculation of cement content once the water.
