Biomineralization of cyanobacteria Synechocystis pevalekii improves the durability properties of cement mortar

Abstract

Keypoints Cyanobacterial Synechocystis pevalekii cells induced calcification on cement mortar. Both live and UV-treated cells increased the compressive strength and reduced the water absorption. Biomineralization by S. pevalekii serves as a low-cost and eco-friendly MICCP technology.
