Abstract
Self-compacting concrete (SCC) has become widely used in the building sector in recent years. Hydrated lime (HL) appears to be a good replacement material for cement due to their strong intrinsic qualities, producing new concrete without impacting its performance or properties. The goal of the current effort is to use this natural material as an alternative cement replacement and examine its impact to the properties of (SCC). In order to
achieve this, a number of factors, including compressive strength, split tensile strength, and flexural strength, have been looked at. Twenty SCC mixes samples in all have been created in three series, each with a different cement and lime replacement rate (0%, 10%, 15%, 20%). Our experimental results showed that adding hydrated lime up to 20% to SCC as a partial replacement for cement in its fresh form produced noticeable characteristics. Concrete’s compressive strength is determined at 7, 28, and 90 days at
room temperature by substituting (0%, 10%, 15%, or 20%). At 90 days of age, split tensile and flexural strengths were discovered with various substitutions of cement and hydrated lime. The experimental study includes a comprehensive research plan made up iv of 12 beams for results on flexural strength, 48 cylinders for results on compressive strength and split tensile strength. Replacement of hydrated lime with cement increases
the water absorption of concrete so for this we use (Sika viscocrete 20HE) as a water reducing agent. In conclusion, after 15% hydrated lime replacement compressive strength decreases and also use of hydrated lime as a replacement of cement increase water cement ratio.
