We consider a general class of quantum-gravity-inspired theories, where the Einstein- Hilbert action is extended through the addition of all terms quadratic in the curvature tensor coupled to a scalar field. This class of theories includes Einstein-Dilaton- Gauss-Bonnet (EDGB) and dynamical Chern-Simons gravity. We consider scalar and gravitational radiation from compact binaries in this theory. We analytically solve the wave equations for the scalar and gravitational radiation under the post- Newtonian formalism and derive the correction in the radiated energy ux. Then, we estimate the expected constraint on this theory from ground-based gravitational wave detectors such as adv. LIGO. We found that they can place considerably stronger constraints on EDGB theory compared to the current solar system experiment.
