Development of grouts for consolidation of old renders
TLDR
In this paper, a study was conducted on the development of lime based grouts for consolidation of renders and plasters detached from the support, where the role of components such as binders, aggregates and admixtures used in the formulations was tested through an outlined series of mechanical and physical tests.About:

Bio-grout based on microbially induced sand solidification by means of asparaginase activity.
TL;DR: Asparaginase-based MICP process for sand bio-grout development using Bacillus megaterium led to significantly less ammonia production compared to urease without compromising with desired properties of a novel grout, and confirmed that biocalcification by means of bacterial asparaginases is a potential solution for geotechnical problems.

A study of traditional blood lime mortar for restoration of ancient buildings
TL;DR: In this article, the performance and mechanism of simulated blood mortars are presented and the results showed that the mortar prepared by blood with lime had better binding strength, waterproof property, weather resistance and curing speed than common lime mortar.

Lime mortar consolidation with nanostructured calcium hydroxide dispersions: the efficacy of different consolidating products for heritage conservation
Anna Arizzi,Anna Arizzi,L. S. Gomez-Villalba,Paula López-Arce,Paula López-Arce,Giuseppe Cultrone,Rafael Fort +6 more
TL;DR: In this article, the authors analyzed the efficacy of dispersions of nanoparticles of calcium hydroxide for consolidating lime mortars, according to three variables: the type of dispersion (three consolidating compounds, CaLoSil ®, NanoreStore ® and Merck ®), the concentration of the dispersion, and the state of the sample (comparison of saturated and non-saturated samples).

Atmospheric NOx removal: study of cement mortars with iron- and vanadium-doped TiO2 as visible light–sensitive photocatalysts
TL;DR: In this paper, the photochemical oxidation (PCO) of atmospheric pollutants such as nitrogen oxides TiO2 as reference catalyst, and two doped titania, Fe-TiO2 and V-Ti2, which were expected to increase the sensitivity of the additives towards the visible light, were studied.

Metakaolin and calcined clays as pozzolans for concrete: a review
B.B. Sabir,S. Wild,J. Bai +2 more
TL;DR: The use of metakaolin (MK) as a pozzolanic material for mortar and concrete has received considerable attention in recent years as mentioned in this paper, which is part of the widely spread attention directed towards the utilisation of wastes and industrial by-products in order to minimise Portland cement consumption, the manufacture of which being environmentally damaging.

Rheology and hardened properties of single-coat render mortars with different types of water retaining agents
TL;DR: In this paper, the effect of two different water retaining agents in single-coat render mortars was compared, and the water retaining agent used in the experiments were cellulose methyl-hydroxypropyl and super absorbent polymers with various contents ranging from 0.05 to 0.15% of the total weight.
