“…The building materials are solids formed by a mixture of different components, which must have a homogeneous spatial composition [14,15]. Because their manufacture is based on mixing solid elements with water, pouring the mixture into a mold, and proceeding to the drying process, these can be considered scattered soli, where air occupies the space occupied by the water during drying process is completed.…”

Building materials must meet several requirements so that they can be used in a given application. These requirements are determined from the measurement of physical properties, depending on the nature of the components. This paper presents a set of mathematical processes and analyses to be carried out for new materials development according to the theory of dispersed or polydispersive systems, including a set of proposed steps to characterize such materials as the criteria for the study. Studies are considered at the microscopic level from the interaction of the elements and the macroscopic level from properties for emulsion cases, including viscosity.

“…Chandra et al [1] reported that the incorporation of the OFI extract increases the plasticity of the cement paste with a consequent decrease in water absorption by the mortar and an improved freeze-thaw resistance of the mortar. Other authors reported that the use of the OFI extract in mortar formulation decreases the compressive strength as a function of W/C [2], slightly increases the flexural strength [3], and may induce a reduction in porosity [4,5].…”

Biobased mortars are gaining interest because of the opportunity to upgrade agricultural byproducts and to reduce the environmental impact of cementitious materials. However, to overcome the drawbacks linked to the use of flax byproducts, such as mucilage and its hygroscopy, it's necessary to study the impact of the water-to-cement ratio and the addition of mucilage on mortars. The W/C ratios range from 0.5 to 0.8 and the mucilage is added anhydrous with cement or pre-dissolved in the water. High W/C ratios affect both fresh and hardened properties of mortars. A high ratio accelerates the setting process and generates more heat released on unmodified mortars while decreasing the induction period. Conversely, when mucilage is added, the setting time is increased due to a poisoning effect affecting the hydrate growth by a chemisorption mechanism on Ca 2+ . This delay is higher as the W/C ratio increases and the mucilage is in-solution. Anhydrous mucilage accelerates the setting until the highest water content is reached. The undissolved polysaccharides of the mucilage cannot impact the hydration process at a W/C ratio below 0.8. Increasing the water content is beneficial for the mortar strength but an excessive W/C ratio is harmful for the unmodified mortar. Mucilage polysaccharides generate a lack of strength compared to the standard. This reduction in strengths is lowered in flexural tests due to an elastic behavior conferred by the mucilage. The changes in properties are not correlated to any mineralogical modification as shown by FTIR and TGA analyses.

“…The nopal cactus (Opuntia ficus-indica), a native plant distributed throughout Latin America, is a natural polymers supplier that has been studied in numerous investigations for its properties, since phenolic compounds had been found in the composition, which can be used in various industries, including pharmaceutical, construction, agrotechnology, bioenergy, and biotechnology industries [12]. One of the most important components of nopal cactus is dietary fiber, which is a rich source of hydrocolloids (pectin and mucilage), named as such because of their great capacity to capture and retain water.…”

In Vitro culture is a technique commonly used for plant research. Nevertheless, it is more expensive than traditional methods of production, due to the use of the culture medium gelling agent called agar. Recent studies have been searching for alternative substances in raw materials with the same characteristics but which can be extracted easier than agar. The dietary fiber of the nopal cactus (Opuntia) is a rich source of hydrocolloids (pectin and mucilage). These hydrocolloids have the ability to gel in combination with the indicated solution. In this chapter, we will focus on the study of the hydrocolloids from nopal cactus to replace agar partially and/or totally as a gelling agent using in vitro culture media benefiting from the molecular structure and mechanical properties of the compounds.
