Concrete is most widely used construction material in the world. Its superior properties make it a suitable material for utilization. Modern age concretes are more durable and have high strengths as compared to old age concretes. However, these high strength concretes presents high shrinkage at early-ages, which is due to low water/binder (w/b) ratios. Keeping in view this problem, this research study is conducted. Mortars were made with cement and silica fume as binders with incorporation of two different size ranges of tea waste particles. Setting time, flow and chemical shrinkage of fresh mortars were investigated. The results showed that the addition of saturated tea waste particles reduced the chemical shrinkage at early ages as compared to the mixes without tea waste particles.
