Mineral additives (zeolites, SiO 2 micro dust etc.) are some of the most prospective components of concrete in the development of new building materials such as high performance concretes, special concretes absorbing heavy metals or suppressing radioactive radiation.
Table 1, reproduced from ACI 212.3, summarizes results from a series of permeability tests performed on concrete mixes with and without three different types of PRAs. Note that these results only indicate the reduction in permeability between the reference and test concrete for each admix type.
Anti-Microbial Additive. MSD specified the use of ConmicShield®, an anti-microbial additive that is mixed directly into concrete and permanently inhibits Thiobacillus growth. MSD Materials Engineer Ron Moore said that MSD first used the additive eight years ago with excellent results on the Maline Drop Shaft, near Chain of Rocks Bridge.
concrete workability. The same applies to the use of puzzolanes as clinker replacement. In the following example, concrete producers complained about the unacceptable short slump life with this particular cement compared to another possible cement supplier. Naturally, production rates and strength development had to remain unchanged.
from freezing of structural concrete frames. Increasing the rate of early-strength development permits earlier removal of forms and earlier opening of construction. Prohibiting use of calcium chloride accelerators is of special concern when project specifications for concrete require 20% to 50% of the portland cement to be replaced …
