Abstract:
In this research mesquite wood powder has been used as an additive to cement to reduce cement micro-cracks, it has been added to five cement samples with different percentage, after the required tests ,it has been founded that the compressive strength stay constant and equal to 5323psi in the range recommended by (API),also the space between particles of cement stay constant equal 32.12 micrometer and it has been founded that the sample No.(3) has the tallest length of micro-cracks equal 28 millimeter also most number of micro-cracks have been founded in sample No.(2) and No.(3) equal to 5 so according to these results, these percentages of mesquite wood powder made the number and length of cement micro-cracks decreased after sample No.(3) although there is increasing in number and length from sample No.(1) to No.(3).
