Strength Possibilities on Fly ash Based Interlock Pavers

Abstract

Interlocking Concrete Block Pavement (ICBP) poses as the most suitable alternative to traditional pavement construction techniques. This is because of the increased advantages in countries wherein durability, and operational or environmental constraints limit the efficiency of the conventional process. The construction industry everywhere faces problems and significant challenges including manpower, quality of productivity, preservation of the environment, mass transportation, water management, raw materials, durability and design life of construction products, chemical resistance, etc. The increased expense on the raw materials for construction is the primary focus of the study. The study aims to search for suitable alternatives that would allow sustainable development. The study emphasizes on the rising costs of construction materials and the necessity to work towards sustainability, alternative construction techniques and materials. Indigenous production of interlocks with mineral admixtures raises the potential applicability of the interlock pavers. To enhance the strength property and keeping sustainability in point of view, fly ash is used as a mineral admixture and partially replaced with cement in various proportions like 0%, 5%, 10%, 15%, 20%, 25%, 30% and 35%. Fourty eight interlock concrete paver blocks were cast and compressive strength for all specimens was calculated and later compared. A notable rise in the strength of the interlock pavers was observed at 15% and 20% replacement levels with fly ash. The optimum level for replacement was determined as 20% of the fly ash.

A Review Study on Composite +8 Structure with Application of Damper on Different Locations Using Time History Analysis

“…The ability of the structure to react to seismic occurrences was improved by a decrease in inertia, which also results in a decrease in maximum acceleration. [17] studied viscous fluid dampers were presented in this paper. To determine the mechanical features and frequency reliance of the damper using various dynamic inputs, several kinds of component tests were conducted.…”

Influence Of Helical Confinement On Crack Development In RCC Beams

“…There are several basic features that must be met for a building to be considered for better serviceability conditions. The construction industry is facing day to day challenges that includes the design of sustainable materials [2]. In building, this material is frequently utilized because of its cheapness and flexibility to be molded into various sizes and shapes.…”

Evaluation of the Strength properties of Sarooj based concrete design

“…There are problems and significant challenges in the construction industry everywhere [2]; the earliest use of cement dates back to the Egyptian civilization. This includes issues such as the number of workers, the quality of their work, the cleanliness of the environment, the reliability of transportation and water supplies, the quality of raw materials, the longevity of construction products, their resistance to chemicals, and much more.…”
