The negative impacts of cement-based material (CBM) production are way bigger than ever
expected. To illustrate the scale of this phenomenon, all the forests in the world, regardless …

To achieve the extended service life of the concrete material, expansive chemicals and
microbial induced calcium carbonate precipitation are used, which induced autonomous …

This paper presents the effect on compressive strength and self-healing capability of
bacterial concrete with the addition of calcium lactate. Compared to normal concrete …

In research on self-healing concrete, the restorative performance can be evaluated by a
wide range of techniques. However, most of these techniques can be challenging to apply to …

Concrete is the most widely used construction material in the world being cement one of its
main components. Cement production accounts for 5-8% of anthropogenic CO 2 emissions …

Microbial-based self-healing of concrete represents innovative technology for improving
micro-crack sealing. Microbial bioactivity can induce calcite-precipitation in concrete, which …

As concrete is a brittle substance, it is prone to cracking, which has major consequences for
the durability of concrete structures [1-3]. Cracks will easily allow for entry of harmful …

Concrete cracks due to several reasons and through the cracks oxygen, water, chlorides
and other aggressive agents can penetrate, decreasing the concrete durability, performance …

Bacteria induced calcium carbonate precipitation based on metabolic conversion of
nutrients has been acknowledged for having potentials in self-healing cement-based …

In this chapter an overview will be given of the biotechnological possibilities for repair of
concrete with focus on application of limestone-producing bacteria and the different …
