Experimental Studies on Durability Studies of Concrete with Partial Replacement of Cement by Water Hyacinth Ash

Abstract

Cement is the main constituent ingredient in concrete. Now days many investigations undergone for substitute of cement due to green houses effect and global warming .Many new products like rice husk ash, egg shell powder, baggage ash, etc are used as an effluent replacement material for cement. The new and Practical material for substitute of cement is water hyacinth ash .Water hyacinth ash (WHA), is used as an effectual replacement of partial cement, and it has been proved in several characteristics of concrete. The main important parameters in concrete are strength, durability and workability. In this paper, 10 % of cement replaced by water hyacinth ash to investigate the effects of WHA on durability and Strength in concretes. On this basis, specimens were engrossed in water and acid to study the absorption property, acid attack and compared to conventional concrete. The test results show that replacement of cement by WHA in concrete has improved the parameters of concrete.

Acoustics of Compressed Earth Blocks Bound Using Sugarcane Bagasse Ash and Water Hyacinth Ash

“…Figure 1 shows some of the modern earth blocks wit aesthetic value, as well as be er mechanical properties that are currently being used in th construction of walls of houses. In the search for alternative binders to cement, many materials have been invest gated, including fly ash, rice husk, silica fume, eggshell, groundnut shell, sugarcane ba gasse ash, cassava powder, waste glass, coal bo om ash, waste marble powder, and waste derived ceramic concrete [13][14][15][16][17][18][19][20][21][22][23]. However, large quantities of these materials that can b used in building reasonable-sized houses may not be easy to find.…”

“…WHA consists mainly o calcium oxide (22.61%), potassium oxide (14.82%), magnesium oxide (14.01%), and silic (4.40%), with a specific gravity of 2.44. According to a study by Murugesh, Balasundaram and Vadivel [25], using WHA in place of some of the cement decreases corrosion an weakens the concrete's resistance to chloride erosion.…”

“…Thus, finding its use in the construction of earth blocks serves as a way of utilising it. In the past, it has been used to make concrete in order to increase the material's permeability and tensile strength [24], as well as the partial replacement of cement in the form of water hyacinth ash (WHA) [16]. WHA consists mainly of calcium oxide (22.61%), potassium oxide (14.82%), magnesium oxide (14.01%), and silica (4.40%), with a specific gravity of 2.44.…”
