This paper presents an experimental study to investigate the influence of super absorbent polymer (SAP) on mechanical, rheological, durability, and microstructural properties of self‐compacting concrete using a comparatively new environmental waste known as granite pulver (GP). The effectiveness of replacing cement by GP at 5, 10, 15, and 20% by weight, was investigated. The SAPs were used at volume fractions of 0.1 to 1% to the GP‐SSC (Granite Pulver‐Self‐cured Self‐compacting Concrete) mixtures to counteract self‐desiccation during the hydration of concrete. Along with the SAP, super plasticizer, and flyash (FA) were also added to improve the workability of the GP‐SSC mixtures. The physical, chemical, and microstructural properties of the cement, GP and flyash samples were determined. From the results, it was found that the GPs along with the SAPs increases the compressive strength by around 0.1%, when a replacement of cement by GP up to 15% was made with an addition of 0.3% of SAP. Similarly, an increase of 9.1% in flexural strength was observed for GP‐SSC mixtures, when 15% of GP along with 0.4% of SAP was added. The addition of SAP beyond 0.4% in GP‐SSC mixtures affects the filling and passing abilities. Therefore, with optimal replacement of cement by GP, the mechanical and durability properties of GP‐SSC mixtures can be improved, reducing the detrimental effects of GPs from the environment. Influence of SAP and GP waste in GP‐SSC mixtures. Analyzed mechanical, rheological, durability, and microstructural properties. Replacement of cement by GP up to 15% is favorable. 0.3% of SAP addition improves the pore structure and strength. Morphological and mineralogical studies prove GP as an effective cement replacement.
Industrialization and urbanization has caused a serious impact on the environment due to the vast consumption of energy and eco‐unsustainable production. Therefore, scientists and engineers are placing more effort to design environmentally sustainable systems. To achieve sustainability, one potential solution is to use renewable resources to produce construction materials. The effect on various amounts of admixed super absorbent polymer (SAP) on microstructural, fresh and hardened properties of autogenous cured concrete incorporating Granite Pulver (GP) have been investigated. For this purpose, a small quantity of Portland cement was replaced by GP as 5, 10, 15, and 20%. The SAP was used at volume fractions of 0.1 to 1% to the GP‐concrete blends to counteract self‐desiccation during the hydration of concrete. Along with the GP, fly ash (FA) was also added as filler to improve the workability of GP‐concrete blends. The chemical and microstructural properties of unprocessed GP, fly ash, and cement samples along with the mechanical properties of GP‐concrete blends were investigated through different tests. A total of 627 specimens were prepared for mechanical testing of GP‐concrete blends. The GP along with the SAP increases the compressive strength and flexural strength in comparison with the control mixture by around 1.6 and 6.8% respectively, when a replacement of cement by GP up to 15% was made with an addition of 0.4% of SAP in the mixture.
