In a randomized block design, the model accounts for variations both due to blocks and treatments. The interaction term is not included because each treatment is replicated only once per block, making it impossible to estimate interaction from this design. Hence, the model includes a constant (overall mean), the effect of the block, and the effect of the treatment.
