The London Advertiser, to which we owe most of our information as to his works, offers to his relatives and friends the sincere sympathy of the public which it represents, and we are sure that the architects of the United States will join with their brethren in Canada in mourning the loss of one who, at so early an age, had conquered for himself so conspicuous a place in his laborious profession. * * * * * Some interesting experiments on concrete arches were made recently, during the construction of the new railway station at Erfurt. Some of the rooms were to be covered with concrete floors, carried on iron beams, while others, of smaller size, were intended to be spanned by arches extending home improvement online from wall to wall. One of the latter, something over seven feet in width, was covered with concrete, flat on top, and forming on the underside a segmental arch, the thickness of the material at the crown of the arch being four inches, and about eleven inches at the springing. The concrete was made of "Germania" Portland cement, mixed dry with gravel, moistened as required, and well rammed on the centring; and home improvement online skew-backs were cut in the brick walls at the springing line, extending two courses higher, so as to give room for the concrete to take a firm hold on the walls. Fourteen days after completion, this floor was loaded with bricks and sacks of cement to the amount of more than six hundred pounds per square foot, without suffering any injury, although, after the load was on, a workman hammered with a pick on the concrete, close to the loaded portion, so as to provoke the cracking of the arch if there had been any tendency to rupture. In the other cases, the concrete arches being turned between iron beams, the strength of the floor was limited by that of the beams, so the extreme load could not be put on; but the curious fact was established that a section of concrete flat on top, and forming a regular segmental arc beneath, was far stronger than one in which a portion of the under surface was parallel to the upper; showing, apparently, that the home improvement online arched form, even with homogeneous concrete, causes the conversion of a large part of a vertical pressure into lateral thrust, reducing by so much the tendency of the load to break the concrete transversely.
