Type III Cement (High Early Strength)
Type III Cement (High Early Strength)
(OP)
Does anyone know any disadvantages of using type III cement (cracking, etc.)? I'm about to be in a time crunch and I don't think I'll be able to wait the 28 days to gain the strength I want.

High-early-sterntg can be obtained by using one or a combination of the following, depending on the age at which specified strength must be achieved and on job conditions:
1. Type III or HE high-early-strength cement
2. High cement content (675 to 1000 lb/yd^3)
3. Low water-cementing materials ration (0.20 to 0.45 by mass)
4. Higher freshly mixed concrete temperature
5. Higher curing temperature
6. Chemical admixtures
7. Silica fume (or other supplementary cementing materials)
8. Steam or autoclave curing
9. Insulation to retain heat of hydration
10. Special rapid hardening cements
I know Type III cement costs more than Type I so you might want to look at some of these other options depending on how much you need to move the schedule up. Also the working time on these early strength mixes can be significantly shorter than regular concrete mixes.
