It’s vital that you know and understand that light-weight aggregates are reactive (higher silica content material) and want a pozzolan to mitigate ASR. It’s among concrete science’s ironic truths: if lightweight aggregates (or any high-silica combination sorts) are used with Portland cement without the mitigating consequences of a reactive pozzolan, the concrete inevitably develops a awful ASR trouble—a reaction among the silica content in the aggregate and also the alkali during the hydrated cement paste. The alkali-silica reaction varieties expansive gels that produce a type of sluggish-motion explosion, map-cracking and finally destroying concrete structures from the inside out.
