Effect of Various Treatment and Drying Methods of Blood Meal Additive on Fresh State Properties of Grouting Materials

Abstract

Grouting is one of the most commonly preferred repair methods used for historic buildings exposed to various deteriorating environmental conditions during their life span. Being that grouting is an irreversible method, it is crucial to determine the original material properties of the historic building to be repaired. In the literature, it is revealed that protein sources have long been used as popular additives to enhance the physical, mechanical, and durability properties of buildings. Specifically, blood additive has been known to have a potential to benefit as a water resisting or air-entraining admixture. Nonetheless, there is a lack of information regarding the use of animal blood in grouting materials, while the impact of blood additive on the properties of lime or cement-based mortars has been investigated recently. In this study, the impact of blood meal incorporation into the lime-based grouting material is discussed in terms of its fresh properties, i.e., fluidity, penetration, and stability. The blood meal samples to be tested were treated with various chemicals to enhance its performance and dried by various drying mechanisms. According to the test results, it was determined that the mixture containing blood meal treated with tri sodium citrate and dried in the drying oven met the requirements of all kinds of fresh state tests and had the potential to be used as a repair material.
