CME allows the user to choose a known quantity of cementitious material OR water and percentages of different types of cementitious products. In this example, the designer is asking CME to target a total water content of 290 pounds and proportion the cement at 50%, Slag at 35%, and f-ash at 15%. The concrete designer knows that the mixtur
CME allows the user to choose a known quantity of cementitious material OR water and percentages of different types of cementitious products. In this example, the designer is asking CME to target a total water content of 290 pounds and proportion the cement at 50%, Slag at 35%, and f-ash at 15%. The concrete designer knows that the mixture needs 290 pounds of water to achieve the desired workability. Click the "Calculate" button and the CME proportions of the cementitious contents & water to the desired W/Cm ratio. The same scenario can be done by fixing the total number of pounds of cementitious waste and allowing the CME to solve the problem of water content.
Auto-Blend up to five aggregates

Auto-Blend up to five aggregates
CME's ability to auto-blend and manipulate the proportioning of the aggregates to automatically adjust the total gradation of aggregates to a desired "Workability and Harshness" target, saves time and improves your concrete design.
About Concrete Mix Evaluator (CME)
Custom Excel Menu
- The CME embraces Excel technology and utilizes a custom menu structure for program navigation, allowing the designer to approach the concrete mixture design from several points of view
Todays concrete includes admixtures
Admixtures are a part of concrete design. Not all admixtures are added using the same approach. Water-reducing admixtures are commonly added as Oz per hundredweight of cementitious material (oz/cwt). Air entraining agents may be dosed as Oz per Yard of concrete (oz/yd). In addition, the water in the admixture may be required to be counted as part of the W/Cm ratio. CME gives the concrete designer that flexibility.

How the CME got started:
Back in 1995, I took a job with a manufacturer of expanded clay lightweight in Southern Georgia—the product used in the concrete block. Having worked for Besser Company (a manufacturer of concrete block equipment), I started writing a program to blend the aggregates for designing concrete block mixes using Microsoft Excel V. The lightweight aggregate was also used as structural lightweight in concrete. One day, I was working at a precast plant; after putting up mixes and weighing and batching nine to ten mixes, I decided that I needed a more systematic approach. I went back to the hotel room and started working on an Excel program that would become known as the "Concrete Solver." In the beginning, I did all the programming, and It was quite fun and rewarding to see other concrete professionals use the program. With the changes in the development of Excel V, Excel 97, Excel 2003, Excel 2007, and now Office/Excel 365 and the updating of Visual Basic (VBA), I hired a VBA programming professional. The latest version is now the "Concrete Mix Evaluator." Your comments and suggestions are more than welcome as they help me continue to create an affordable tool for the concrete professional. Proportioning concrete has been my passion; I was the chair for ACI 211 Proportioning Concrete Mixtures (2007-2014), chair for ASTM C01.29 Sulfate Resistance (2016-2018), and received the Mell C. Marshall award from the American Concrete Pipe Association in 2023.
