What is the effect of water content on the concrete workability?4 answersThe water content in concrete has a significant effect on its workability. Reducing the water content can lead to an increase in flow and penetration time, as well as a decrease in volume changes. However, using wastewater as a replacement for potable water in concrete mixing can reduce workability, and the addition of a superplasticizer may be necessary to maintain adequate workability. On the other hand, increasing the water content can improve the fluidity of recycled aggregate concrete (RAC). Chemical admixtures can also be used to reduce the water to cement ratio (w/c) without affecting workability, allowing for higher density of the cement paste. Overall, the water content plays a crucial role in the workability of concrete, and it needs to be carefully controlled and adjusted depending on the specific requirements of the application.
Is water content important in the extraction of plant?5 answersWater content is important in the extraction of plant components. Different extraction methods yield different results depending on the water content of the plant material. For example, in the extraction of paclitaxel from plant cell cultures, the addition of a small amount of water improved the efficiency of microwave-assisted extraction (MAE). In another study, the isotopic composition of soil water extracted from different types of soil was found to be less affected by the extraction methods as the water content increased. Additionally, the development of water-based strategies for the extraction of metabolites from plants has shown that technologies achieving subcritical water conditions can increase extraction rates and yields. Overall, the water content of the plant material plays a significant role in the efficiency and effectiveness of extraction methods.
Is ther influence of water content to the strength of the soil?2 answersWater content has a significant influence on the strength of soil. The strength-time relation of unfired soil-lime bricks showed that bricks with lower soil water content had better strength performances compared to those with higher soil water content. The influence of water content on the mechanical properties of soil was studied using miniature penetration tests, which revealed that the penetration strength decreases progressively with increasing water content above a critical point, and decreases progressively with decreasing water content below the critical point. Saline soil samples tested in the laboratory showed that shearing strength decreases initially and then increases with increasing salt content, while shearing strength parameters reduce with increasing water content. Soil strength was found to be a possible indicator of soil water content, with better agreement between predicted and measured water contents at Proctor Test densities compared to cultivated field densities. An increase in soil water content results in a decrease in electrical resistivity, with the clearest relationship observed below the range of capillary-film water.
How does water content affect the growth of the plant?5 answersWater content has a significant impact on plant growth. In general, plants require an optimum level of soil water content to support their growth. Insufficient water content can lead to reduced plant growth and induce the production of secondary metabolites as a self-defense mechanism. On the other hand, excessive water content can also negatively affect plant growth. The effect of water content on plant growth can be influenced by factors such as the type of plant and the availability of nutrients in the soil. Additionally, the presence of plants can affect the response of soil microbes to water content, with higher respiration rates observed in planted soil compared to unplanted soil at low water content. Overall, maintaining an appropriate water content in the soil is crucial for promoting optimal plant growth and development.
