Warp and weft yarns lie to a certain extent in a wavy form in a fabric. There is, therefore, a difference in length between straightened yarns and the yarns in the wavy form in the fabric, both in warp and weft direction. In order to be able to produce the fabric required, information is needed for predicting the length, width and mass per unit area of the fabric. This difference in length between the yarn and the fabric is usually referred to as crimp, a parameter which is significant for the structure of the fabric and also for the pore shape and size. When the fabric is loaded there is often a change in the ratio of the crimp of the warp and weft system. This change is referred to as crimp interchange. Crimp affects the mechanical properties of the fabric.  1, record 5, English, - crimp%20interchange

The chemistry of pore fluids is directly related to the nature of the binder, to its content in soluble alkali oxides and to the water/binder ratio. Experimental data has mainly been obtained with pure pastes or mortars and measured contents of OH-ions were between 0. 2 and 0. 8 M under these conditions, corresponding to pHs of around 12. 8 to 13. 7. The main cations are Na+ and K+, in equivalent amounts :[Na+] + [K+]=[OH-] This is why the first member(alkali cations) is often confused-sometimes incorrectly-with the second(alkalis or OH-ions).  1, record 7, English, - alkali%20cation

[...] Les cations principaux sont Na+ et K+, de sorte que le bilan ionique simplifié s'écrit : [Na+] + [K+] = [OH-] C'est pourquoi le premier membre (les alcalins) est souvent assimilé - et quelquefois abusivement - au deuxième (les alcalis).  1, record 7, French, - alcalin
