Sustainable concrete mix design for a target strength and service life . Fig. 1 Effect of SCM utilization in CO. 2. emissions, after (Ecosmart concrete 2008) design in order to safeguard certain concrete strength and service life requirements. The challenge
The CivilWeb Concrete Mix Design Spreadsheet Excel allows the designer to complete the design of a concrete mix to suit a number of different specifiions. The spreadsheet uses a small number of mandatory fields such as target characteristic compressive strength, target slump and aggregate types which should be known before the concrete mix design begins.
American Concrete Institute Method of Mix Design (ACI–) This method of proportioning was first published in 1944 by ACI committee 613. In 1954 the method was revised to include, among other modifiions, the use of entrained air. In 1970, the method of mix design became the responsibility of ACI committee 211.
· CONCRETE MIX DESIGN (GRADE M60) (a) DESIGN STIPULATION: Target strength = 60Mpa Max size of aggregate used = mm Specific gravity of cement = Specific gravity of fine aggregate () = Specific gravity of Coarse aggregate () = Dry Rodded Bulk Density of fine aggregate = 1726 Kg/m3 Dry Rodded Bulk [.]

· Mix concrete design spreadsheet plays a vital role in civil engineering construction works.. You need to find the accurate amount of quantity for any construction site and this concrete mix design spreadsheet will help you to achieve the same. And the best thing is this is in excel format sheet.
TxDOT developed a Concrete Mix Design Guidance document that provides useful information on mix design, production considerations, and testing requirements. Concrete mix design can be facilitated by using the Mix Design spreadsheet developed by TxDOT. The mix design must be formally approved by an engineer. Anchor: #i.
Concrete mix ratio for beams. As we know that Beam is RCC structure so we can use minimum grade of M20 grade and concrete mix ratio 1::3 for beams maximum grade of concrete m25, M30 and much higher are used as per design for beam. 1::3 (m20) is concrete mix ratio used for beam. Concrete mix ratio for Foundation.
concrete mix design should be by the civil Engineer involved. In recent year we have witness allot of concrete structural failure either during construction, after the completion or few year of the project age of completion, without satisfying design age of the project life (Yunusa, 2011). 2 ...
