Abstract The growing demand and production of cement have created a significant impact on the environment and the cement production has required huge energy consumptions. Therefore, Pakistan is facing a serious energy crisis. Thus, the researchers are engaged for introducing agricultural/industrial waste materials which possess cementitious properties to reduce not only cement production, but it reduces energy consumption, and helps to protect the environment. The experimental goal of this work was to investigate the fresh and hardened concrete inclusion with MHA as cement replacement at proportions such as 0%, 5%, 10%, 15%, and 20%. In this investigational work, total 180 concrete specimens were prepared with a targeted strength of 25 MPa. However, cube specimen was used for compressive strength, cylindrical samples were used for investigating the splitting tensile strength and prism specimen used for flexural strength of concrete. The results showed the compressive strength was achieved by 30.24 MPa and 28.21 MPa at 5% and 10% of MHA as compared to targeted strength of 25 MPa after 90 days. Similarly, splitting tensile and flexural strength was estimated by 2.64 MPa and 4.26 MPa at 10% of MHA as cement replacement material in concrete after 28 days respectively. Moreover, the water absorption and density of concrete was reduced with rise in content of MHA after 28 days respectively. Besides, the slump was declined as the content of MHA rises.

1 Introduction Concrete is an artificial building material that is most frequently used for the construction of various building structures [1]. Since its inception, the demand and importance of concrete in the construction industry has continued to grow. According to Lomborg [2], the concrete is used more than any other manmade material on earth [3]. In 2005, Concrete is made about 6 × 109 ms3 per year in country like China which consumes round by 40% of the world’s cement production [4]. The rate of concrete is comparatively high due to production cost of its

chief constituent, ordinary Portland cement (OPC). Malhorta et al. [5] stated that the use of cement increased day by day and its production is measured by 3rd largest carbon-dioxide (CO2) producer where the production of one-ton Portland cement releases about 1 to 1.25 ton of carbon dioxide into the environment.
