    Hello, I bought this block and performed some experiments for our reserach. Could you please say what mix design was used to make these blocks? I mean what is the ratio of cement:sand:stone, what other materials were used? I appreciate your response.

                    These made for an easy transition from garage floor to the entry door without having to pay someone to pour a concrete step. They are perfect!

                      It's a good little brick, well behaved and sits on my front stoop with 3 of his brick friends to create an extra step for me to enter my home. I would recommend this brick to others. It definitely meets my standards.??

                      Versatile blocks.
                      I have used these blocks throughout the years for multiple projects. Most recent, I used them as risers for steps to a shed.

                        It's a block, not sure what else to say really. They made a nice wood storage box opening on the base of what will be a brick pizza oven.

                        I cut six of these in half and used them as footings for my shed. They are solid and got the job done. I laid them on a bed of 3-4" of gravel.
