Bridge Low Slump Concrete Overlay Mix Design

12-03-2020  - Develop an updated concrete overlay mix design that: (a) exhibits less early-age cracking, (b) has low permeability, and (c) can be batched with a mobile concrete mixer. By developing a new mix design outside of a construction contract, MnDOT can better manage risks to schedule and cost associated with having a mix design approved after contract award.

Development of Optimal Concrete Mix Designs for Bridge Decks

Inappropriate concrete mix designs may be one of the primary factors responsible for long-term durability problems of bridge decks. Therefore, there is a pressing need to develop a better concrete mix design for bridge deck applications, especially suitable for local applications in Colorado. There were two phases in this project.

Concrete Mix Design Just Got Easier Giatec Scientific Inc.

25-02-2020  Concrete Mix Design. Concrete mix design is often mistakenly referred to as “cement mix design.” However, cement is simply one of the ingredients of concrete. It is a binding substance that allows concrete to set, harden, and adhere to other materials. Therefore, it cannot and should not be used interchangeably with concrete mix design.

Using Styrene-Butadiene Latex in Concrete Overlays

MIX DESIGN The inclusion of latex in concrete reduces water demand of the mix, achieving a workable slump (4-6 in.) at a water­ cement ratio of 0.40 or less. This includes the water in the latex, typically 52 percent by weight. The primary criteria for LMC overlays are workability in the plastic state, bond and low permeability in the hardened ...
